partitions: msdos: fix one-byte get_unaligned()
[ Upstream commit 1b1774998b2dec837a57d729d1a22e5eb2d6d206 ]
A simplification of get_unaligned() clashes with callers that pass
in a character pointer, causing a harmless warning like:
block/partitions/msdos.c: In function 'msdos_partition':
include/asm-generic/unaligned.h:13:22: warning: 'packed' attribute ignored for field of type 'u8' {aka 'unsigned char'} [-Wattributes]
Remove the SYS_IND() macro with the get_unaligned() call
and just use the ->ind field directly.

UPSTREAM: block, bfq: set next_rq to waker_bfqq->next_rq in waker injection
Since commit c5089591c3ba ("block, bfq: detect wakers and
unconditionally inject their I/O"), when the in-service bfq_queue, say
Q, is temporarily empty, BFQ checks whether there are I/O requests to
inject (also) from the waker bfq_queue for Q. To this goal, the value
pointed by bfqq->waker_bfqq->next_rq must be controlled. However, the
current implementation mistakenly looks at bfqq->next_rq, which
instead points to the next request of the currently served queue.
This mistake evidently causes losses of throughput in scenarios with
waker bfq_queues.
This commit corrects this mistake.

blk-wbt: introduce a new disable state to prevent false positive by rwb_enabled()
[ Upstream commit 1d0903d61e9645c6330b94247b96dd873dfc11c8 ]
Now that we disable wbt by simply zero out rwb->wb_normal in
wbt_disable_default() when switch elevator to bfq, but it's not safe
because it will become false positive if we change queue depth. If it
become false positive between wbt_wait() and wbt_track() when submit
write request, it will lead to drop rqw->inflight to -1 in wbt_done(),
which will end up trigger IO hung. Fix this issue by introduce a new
state which mean the wbt was disabled.

block: avoid double io accounting for flush request
[ Upstream commit 84da7acc3ba53af26f15c4b0ada446127b7a7836 ]
For flush request, rq->end_io() may be called two times, one is from
timeout handling(blk_mq_check_expired()), another is from normal
completion(__blk_mq_end_request()).
Move blk_account_io_flush() after flush_rq->ref drops to zero, so
io accounting can be done just once for flush request.

block: fix discard request merge
[ Upstream commit 2705dfb2094777e405e065105e307074af8965c1 ] ll_new_hw_segment() is reached only in case of single range discard merge, and we don't have max discard segment size limit actually, so it is wrong to run the following check: if (req->nr_phys_segments + nr_phys_segs > blk_rq_get_max_segments(req)) it may be always false since req->nr_phys_segments is initialized as one, and bio's segment count is still 1, blk_rq_get_max_segments(reg) is 1 too. Fix the issue by not doing the check and bypassing the calculation of discard request's nr_phys_segments. Based on analysis from Wang Shanker.

[16687.163549] pc : __rq_qos_track+0x38/0x60 or [ 997.690455] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000020 ... [ 997.850347] pc : __rq_qos_done+0x2c/0x50 Turns out it is caused by race between adding rq qos(wbt) and normal IO because rq_qos_add can be run when IO is being submitted, fix this issue by freezing queue before adding/deleting rq qos to queue. rq_qos_exit() needn't to freeze queue because it is called after queue has been frozen. iolatency calls rq_qos_add() during allocating queue, so freezing won't add delay because queue usage refcount works at atomic mode at that time. iocost calls rq_qos_add() when writing cgroup attribute file, that is fine to freeze queue at that time since we usually freeze queue when storing to queue sysfs attribute, meantime iocost only exists on the root cgroup. wbt_init calls it in blk_register_queue() and queue sysfs attribute store(queue_wb_lat_store() when write it 1st time in case of !BLK_WBT_MQ), the following patch will speedup the queue freezing in wbt_init.

blk-mq: clear stale request in tags->rq[] before freeing one request pool
[ Upstream commit bd63141d585bef14f4caf111f6d0e27fe2300ec6 ] refcount_inc_not_zero() in bt_tags_iter() still may read one freed request. Fix the issue by the following approach: 1) hold a per-tags spinlock when reading ->rqs[tag] and calling refcount_inc_not_zero in bt_tags_iter() 2) clearing stale request referred via ->rqs[tag] before freeing request pool, the per-tags spinlock is held for clearing stale ->rq[tag] So after we cleared stale requests, bt_tags_iter() won't observe freed request any more, also the clearing will wait for pending request reference. The idea of clearing ->rqs[] is borrowed from John Garry's previous patch and one recent David's patch.

blk-mq: grab rq->refcount before calling ->fn in blk_mq_tagset_busy_iter
[ Upstream commit 2e315dc07df009c3e29d6926871f62a30cfae394 ] Grab rq->refcount before calling ->fn in blk_mq_tagset_busy_iter(), and this way will prevent the request from being re-used when ->fn is running. The approach is same as what we do during handling timeout. Fix request use-after-free(UAF) related with completion race or queue releasing: - If one rq is referred before rq->q is frozen, then queue won't be frozen before the request is released during iteration. - If one rq is referred after rq->q is frozen, refcount_inc_not_zero() will return false, and we won't iterate over this request. However, still one request UAF not covered: refcount_inc_not_zero() may read one freed request, and it will be handled in next patch.

ANDROID: Revert "scsi: block: Do not accept any requests while suspended"
Commit "block: Do not accept any requests while suspended" broke the UFS
driver. In the upstream kernel this has been fixed by commit b294ff3e3449
("scsi: ufs: core: Enable power management for wlun"). Backporting that
commit or backporting the entire v5.14-rc1 UFS driver is too risky.
Hence revert the block layer patch that is incompatible with the v5.10
UFS driver power management code.
This reverts commit

FROMGIT: block/mq-deadline: Prioritize high-priority requests
While one or more requests with a certain I/O priority are pending, do not
dispatch lower priority requests. Dispatch lower priority requests anyway
after the "aging" time has expired.
This patch has been tested as follows:
modprobe scsi_debug ndelay=1000000 max_queue=16 &&
sd='' &&
while [ -z "$sd" ]; do
sd=/dev/$(basename /sys/bus/pseudo/drivers/scsi_debug/adapter*/host*/target*/*/block/*)
done &&
echo $((100*1000)) > /sys/block/$sd/queue/iosched/aging_expire &&
cd /sys/fs/cgroup/blkio/ &&
echo $$ >cgroup.procs &&
echo restrict-to-be >blkio.prio.class &&
mkdir -p hipri &&
cd hipri &&
echo none-to-rt >blkio.prio.class &&
{ max-iops -a1 -d32 -j1 -e mq-deadline $sd >& ~/low-pri.txt & } &&
echo $$ >cgroup.procs &&
max-iops -a1 -d32 -j1 -e mq-deadline $sd >& ~/hi-pri.txt
Result:
* 11000 IOPS for the high-priority job
* 40 IOPS for the low-priority job
If the aging expiry time is changed from 100s into 0, the IOPS results change
into 6712 and 6796 IOPS.
The max-iops script is a script that runs fio with the following arguments:
--bs=4K --gtod_reduce=1 --ioengine=libaio --ioscheduler=${arg_e} --runtime=60
--norandommap --rw=read --thread --buffered=0 --numjobs=${arg_j}
--iodepth=${arg_d} --iodepth_batch_submit=${arg_a}
--iodepth_batch_complete=$((arg_d / 2)) --name=${positional_argument_1}

FROMGIT: block/mq-deadline: Micro-optimize the batching algorithm
When dispatching the first request of a batch, the deadline_move_request() call clears .next_rq[] for the opposite data direction. .next_rq[] is not restored when changing data direction. Fix this by not clearing .next_rq[] and by keeping track of the data direction of a batch in a variable instead. This patch is a micro-optimization because: - The number of deadline_next_request() calls for the read direction is halved. - The number of times that deadline_next_request() returns NULL is reduced.

FROMGIT: blk-mq: Improve performance of non-mq IO schedulers with multiple HW queues
Currently when non-mq aware IO scheduler (BFQ, mq-deadline) is used for
a queue with multiple HW queues, the performance it rather bad. The
problem is that these IO schedulers use queue-wide locking and their
dispatch function does not respect the hctx it is passed in and returns
any request it finds appropriate. Thus locality of request access is
broken and dispatch from multiple CPUs just contends on IO scheduler
locks. For these IO schedulers there's little point in dispatching from
multiple CPUs. Instead dispatch always only from a single CPU to limit
contention.
Below is a comparison of dbench runs on XFS filesystem where the storage
is a raid card with 64 HW queues and to it attached a single rotating
disk. BFQ is used as IO scheduler:
clients MQ SQ MQ-Patched
Amean 1 39.12 (0.00%) 43.29 * -10.67%* 36.09 * 7.74%*
Amean 2 128.58 (0.00%) 101.30 * 21.22%* 96.14 * 25.23%*
Amean 4 577.42 (0.00%) 494.47 * 14.37%* 508.49 * 11.94%*
Amean 8 610.95 (0.00%) 363.86 * 40.44%* 362.12 * 40.73%*
Amean 16 391.78 (0.00%) 261.49 * 33.25%* 282.94 * 27.78%*
Amean 32 324.64 (0.00%) 267.71 * 17.54%* 233.00 * 28.23%*
Amean 64 295.04 (0.00%) 253.02 * 14.24%* 242.37 * 17.85%*
Amean 512 10281.61 (0.00%) 10211.16 * 0.69%* 10447.53 * -1.61%*
Numbers are times so lower is better. MQ is stock 5.10-rc6 kernel. SQ is
the same kernel with megaraid_sas.host_tagset_enable=0 so that the card
advertises just a single HW queue. MQ-Patched is a kernel with this
patch applied.
You can see multiple hardware queues heavily hurt performance in
combination with BFQ. The patch restores the performance.

FROMGIT: blk-mq: clear stale request in tags->rq[] before freeing one request pool
refcount_inc_not_zero() in bt_tags_iter() still may read one freed request. Fix the issue by the following approach: 1) hold a per-tags spinlock when reading ->rqs[tag] and calling refcount_inc_not_zero in bt_tags_iter() 2) clearing stale request referred via ->rqs[tag] before freeing request pool, the per-tags spinlock is held for clearing stale ->rq[tag] So after we cleared stale requests, bt_tags_iter() won't observe freed request any more, also the clearing will wait for pending request reference. The idea of clearing ->rqs[] is borrowed from John Garry's previous patch and one recent David's patch.

FROMGIT: blk-mq: grab rq->refcount before calling ->fn in blk_mq_tagset_busy_iter
Grab rq->refcount before calling ->fn in blk_mq_tagset_busy_iter(), and this way will prevent the request from being re-used when ->fn is running. The approach is same as what we do during handling timeout. Fix request use-after-free(UAF) related with completion race or queue releasing: - If one rq is referred before rq->q is frozen, then queue won't be frozen before the request is released during iteration. - If one rq is referred after rq->q is frozen, refcount_inc_not_zero() will return false, and we won't iterate over this request. However, still one request UAF not covered: refcount_inc_not_zero() may read one freed request, and it will be handled in next patch.

blk-mq: Swap two calls in blk_mq_exit_queue()
[ Upstream commit 630ef623ed26c18a457cdc070cf24014e50129c2 ]
If a tag set is shared across request queues (e.g. SCSI LUNs) then the
block layer core keeps track of the number of active request queues in
tags->active_queues. blk_mq_tag_busy() and blk_mq_tag_idle() update that
atomic counter if the hctx flag BLK_MQ_F_TAG_QUEUE_SHARED is set. Make
sure that blk_mq_exit_queue() calls blk_mq_tag_idle() before that flag is
cleared by blk_mq_del_queue_tag_set().

kyber: fix out of bounds access when preempted
[ Upstream commit efed9a3337e341bd0989161b97453b52567bc59d ]
__blk_mq_sched_bio_merge() gets the ctx and hctx for the current CPU and
passes the hctx to ->bio_merge(). kyber_bio_merge() then gets the ctx
for the current CPU again and uses that to get the corresponding Kyber
context in the passed hctx. However, the thread may be preempted between
the two calls to blk_mq_get_ctx(), and the ctx returned the second time
may no longer correspond to the passed hctx. This "works" accidentally
most of the time, but it can cause us to read garbage if the second ctx
came from an hctx with more ctx's than the first one (i.e., if
ctx->index_hw[hctx->type] > hctx->nr_ctx).
This manifested as this UBSAN array index out of bounds error reported
by Jakub:

Only Kyber uses the hctx, so fix it by passing the request_queue to

map the queues itself to avoid the mismatch.

blk-iocost: fix weight updates of inner active iocgs
commit e9f4eee9a0023ba22db9560d4cc6ee63f933dae8 upstream.
When the weight of an active iocg is updated, weight_updated() is called
which in turn calls __propagate_weights() to update the active and inuse
weights so that the effective hierarchical weights are update accordingly.
The current implementation is incorrect for inner active nodes. For an
active leaf iocg, inuse can be any value between 1 and active and the
difference represents how much the iocg is donating. When weight is updated,
as long as inuse is clamped between 1 and the new weight, we're alright and
this is what __propagate_weights() currently implements.
However, that's not how an active inner node's inuse is set. An inner node's
inuse is solely determined by the ratio between the sums of inuse's and
active's of its children - ie. they're results of propagating the leaves'
active and inuse weights upwards. __propagate_weights() incorrectly applies
the same clamping as for a leaf when an active inner node's weight is
updated. Consider a hierarchy which looks like the following with saturating
workloads in AA and BB.
R
/ \
A B
| |
AA BB
1. For both A and B, active=100, inuse=100, hwa=0.5, hwi=0.5.
2. echo 200 > A/io.weight
3. __propagate_weights() update A's active to 200 and leave inuse at 100 as
it's already between 1 and the new active, making A:active=200,
A:inuse=100. As R's active_sum is updated along with A's active,
A:hwa=2/3, B:hwa=1/3. However, because the inuses didn't change, the
hwi's remain unchanged at 0.5.
4. The weight of A is now twice that of B but AA and BB still have the same
hwi of 0.5 and thus are doing the same amount of IOs.
Fix it by making __propgate_weights() always calculate the inuse of an
active inner iocg based on the ratio of child_inuse_sum to child_active_sum.

FROMGIT: block: avoid double io accounting for flush request
For flush request, rq->end_io() may be called two times, one is from
timeout handling(blk_mq_check_expired()), another is from normal
completion(__blk_mq_end_request()).
Move blk_account_io_flush() after flush_rq->ref drops to zero, so
io accounting can be done just once for flush request.

UPSTREAM: block: fix inflight statistics of part0
The inflight of partition 0 doesn't include inflight IOs to all
sub-partitions, since currently mq calculates inflight of specific
partition by simply camparing the value of the partition pointer.
Thus the following case is possible:
$ cat /sys/block/vda/inflight
0 0
$ cat /sys/block/vda/vda1/inflight
0 128
While single queue device (on a previous version, e.g. v3.10) has no
this issue:
$cat /sys/block/sda/sda3/inflight
0 33
$cat /sys/block/sda/inflight
0 33
Partition 0 should be specially handled since it represents the whole
disk. This issue is introduced since commit

BACKPORT: bio: limit bio max size
bio size can grow up to 4GB when muli-page bvec is enabled.
but sometimes it would lead to inefficient behaviors.
in case of large chunk direct I/O, - 32MB chunk read in user space -
all pages for 32MB would be merged to a bio structure if the pages
physical addresses are contiguous. it makes some delay to submit
until merge complete. bio max size should be limited to a proper size.
When 32MB chunk read with direct I/O option is coming from userspace,
kernel behavior is below now in do_direct_IO() loop. it's timeline.
| bio merge for 32MB. total 8,192 pages are merged.
| total elapsed time is over 2ms.
|------------------ ... ----------------------->|
| 8,192 pages merged a bio.
| at this time, first bio submit is done.
| 1 bio is split to 32 read request and issue.
|--------------->
|--------------->
|--------------->
......
|--------------->
|--------------->|
total 19ms elapsed to complete 32MB read done from device. |
If bio max size is limited with 1MB, behavior is changed below.
| bio merge for 1MB. 256 pages are merged for each bio.
| total 32 bio will be made.
| total elapsed time is over 2ms. it's same.
| but, first bio submit timing is fast. about 100us.
|--->|--->|--->|---> ... -->|--->|--->|--->|--->|
| 256 pages merged a bio.

| and 1 read request is issued for 1 bio.
|--------------->
|--------------->
|--------------->
......
|--------------->
|--------------->|
total 17ms elapsed to complete 32MB read done from device. |
As a result, read request issue timing is faster if bio max size is limited.
Current kernel behavior with multipage bvec, super large bio can be created.
And it lead to delay first I/O request issue.

block: only update parent bi_status when bio fail
[ Upstream commit 3edf5346e4f2ce2fa0c94651a90a8dda169565ee ]
For multiple split bios, if one of the bio is fail, the whole
should return error to application. But we found there is a race
between bio_integrity_verify_fn and bio complete, which return
io success to application after one of the bio fail. The race as
following:
split bio(READ) kworker
nvme_complete_rq
blk_update_request //split error=0
bio_endio
bio_integrity_endio
queue_work(kintegrityd_wq, &bip->bip_work);
bio_integrity_verify_fn
bio_endio //split bio
__bio_chain_endio
if (!parent->bi_status)
<interrupt entry>
nvme_irq
blk_update_request //parent error=7
req_bio_endio
bio->bi_status = 7 //parent bio
<interrupt exit>
parent->bi_status = 0
parent->bi_end_io() // return bi_status=0
The bio has been split as two: split and parent. When split
bio completed, it depends on kworker to do endio, while
bio_integrity_verify_fn have been interrupted by parent bio
complete irq handler. Then, parent bio->bi_status which have
been set in irq handler will overwrite by kworker.
In fact, even without the above race, we also need to conside
the concurrency beteen mulitple split bio complete and update
the same parent bi_status. Normally, multiple split bios will
be issued to the same hctx and complete from the same irq
vector. But if we have updated queue map between multiple split
bios, these bios may complete on different hw queue and different
irq vector. Then the concurrency update parent bi_status may
cause the final status error.

block: recalculate segment count for multi-segment discards correctly
[ Upstream commit a958937ff166fc60d1c3a721036f6ff41bfa2821 ]
When a stacked block device inserts a request into another block device
using blk_insert_cloned_request, the request's nr_phys_segments field gets
recalculated by a call to blk_recalc_rq_segments in
blk_cloned_rq_check_limits. But blk_recalc_rq_segments does not know how to
handle multi-segment discards. For disk types which can handle
multi-segment discards like nvme, this results in discard requests which
claim a single segment when it should report several, triggering a warning
in nvme and causing nvme to fail the discard from the invalid state.

This patch fixes blk_recalc_rq_segments to be aware of devices which can
have multi-segment discards. It calculates the correct discard segment
count by counting the number of bio as each discard bio is considered its
own segment.

block: Suppress uevent for hidden device when removed
[ Upstream commit 9ec491447b90ad6a4056a9656b13f0b3a1e83043 ] register_disk() suppress uevents for devices with the GENHD_FL_HIDDEN but enables uevents at the end again in order to announce disk after possible partitions are created. When the device is removed the uevents are still on and user land sees 'remove' messages for devices which were never 'add'ed to the system. KERNEL[95481.571887] remove /devices/virtual/nvme-fabrics/ctl/nvme5/nvme0c5n1 (block) Let's suppress the uevents for GENHD_FL_HIDDEN by not enabling the uevents at all.

blk-cgroup: Fix the recursive blkg rwstat
[ Upstream commit 4f44657d74873735e93a50eb25014721a66aac19 ]
The current blkio.throttle.io_service_bytes_recursive doesn't
work correctly.
As an example, for the following blkcg hierarchy:
(Made 1GB READ in test1, 512MB READ in test2)
test
/ \
test1 test2
$ head -n 1 test/test1/blkio.throttle.io_service_bytes_recursive
8:0 Read 1073684480
$ head -n 1 test/test2/blkio.throttle.io_service_bytes_recursive
8:0 Read 537448448
$ head -n 1 test/blkio.throttle.io_service_bytes_recursive
8:0 Read 537448448
Clearly, above data of "test" reflects "test2" not "test1"+"test2".
Do the correct summary in blkg_rwstat_recursive_sum().

block: Discard page cache of zone reset target range
commit e5113505904ea1c1c0e1f92c1cfa91fbf4da1694 upstream.
When zone reset ioctl and data read race for a same zone on zoned block
devices, the data read leaves stale page cache even though the zone
reset ioctl zero clears all the zone data on the device. To avoid
non-zero data read from the stale page cache after zone reset, discard
page cache of reset target zones in blkdev_zone_mgmt_ioctl(). Introduce
the helper function blkdev_truncate_zone_range() to discard the page
cache. Ensure the page cache discarded by calling the helper function
before and after zone reset in same manner as fallocate does.
This patch can be applied back to the stable kernel version v5.10.y.
Rework is needed for older stable kernels.

blk-settings: align max_sectors on "logical_block_size" boundary
commit 97f433c3601a24d3513d06f575a389a2ca4e11e4 upstream. We get I/O errors when we run md-raid1 on the top of dm-integrity on the top of ramdisk. device-mapper: integrity: Bio not aligned on 8 sectors: 0xff00, 0xff device-mapper: integrity: Bio not aligned on 8 sectors: 0xff00, 0xff device-mapper: integrity: Bio not aligned on 8 sectors: 0xffff, 0x1 device-mapper: integrity: Bio not aligned on 8 sectors: 0xffff, 0x1 device-mapper: integrity: Bio not aligned on 8 sectors: 0x8048, 0xff device-mapper: integrity: Bio not aligned on 8 sectors: 0x8147, 0xff device-mapper: integrity: Bio not aligned on 8 sectors: 0x8246, 0xff device-mapper: integrity: Bio not aligned on 8 sectors: 0x8345, 0xbb The ramdisk device has logical_block_size 512 and max_sectors 255. The dm-integrity device uses logical_block_size 4096 and it doesn't affect the "max_sectors" value - thus, it inherits 255 from the ramdisk. So, we have a device with max_sectors not aligned on logical_block_size. The md-raid device sees that the underlying leg has max_sectors 255 and it will split the bios on 255-sector boundary, making the bios unaligned on logical_block_size. In order to fix the bug, we round down max_sectors to logical_block_size.

block: reopen the device in blkdev_reread_part
[ Upstream commit 4601b4b130de2329fe06df80ed5d77265f2058e5 ]
Historically the BLKRRPART ioctls called into the now defunct ->revalidate
method, which caused the sd driver to check if any media is present.
When the ->revalidate method was removed this revalidation was lost,
leading to lots of I/O errors when using the eject command. Fix this by
reopening the device to rescan the partitions, and thus calling the
revalidation logic in the sd driver.

bfq: Avoid false bfq queue merging
commit 41e76c85660c022c6bf5713bfb6c21e64a487cec upstream.
bfq_setup_cooperator() uses bfqd->in_serv_last_pos so detect whether it
makes sense to merge current bfq queue with the in-service queue.
However if the in-service queue is freshly scheduled and didn't dispatch
any requests yet, bfqd->in_serv_last_pos is stale and contains value
from the previously scheduled bfq queue which can thus result in a bogus
decision that the two queues should be merged. This bug can be observed
for example with the following fio jobfile:
[global]
direct=0
ioengine=sync
invalidate=1
size=1g
rw=read
[reader]
numjobs=4
directory=/mnt
where the 4 processes will end up in the one shared bfq queue although
they do IO to physically very distant files (for some reason I was able to
observe this only with slice_idle=1ms setting).
Fix the problem by invalidating bfqd->in_serv_last_pos when switching
in-service queue.

UPSTREAM: block/keyslot-manager: introduce devm_blk_ksm_init()
Add a resource-managed variant of blk_ksm_init() so that drivers don't have to worry about calling blk_ksm_destroy(). Note that the implementation uses a custom devres action to call blk_ksm_destroy() rather than switching the two allocations to be directly devres-managed, e.g. with devm_kmalloc(). This is because we need to keep zeroing the memory containing the keyslots when it is freed, and also because we want to continue using kvmalloc() (and there is no devm_kvmalloc()).

ANDROID: dm: sync inline crypto support with patches going upstream
Replace the following patches with upstream versions (well, almost upstream; as of 2021-02-12 they are queued for 5.12 at https://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git/log/?h=for-next): ANDROID-dm-add-support-for-passing-through-inline-crypto-support.patch ANDROID-dm-enable-may_passthrough_inline_crypto-on-some-targets.patch ANDROID-block-Introduce-passthrough-keyslot-manager.patch Also, resolve conflicts with the following non-upstream patches for hardware-wrapped key support. Notably, we need to handle the field blk_keyslot_manager::features in a few places: ANDROID-block-add-hardware-wrapped-key-support.patch ANDROID-dm-add-support-for-passing-through-derive_raw_secret.patch Finally, update non-upstream device-mapper targets (dm-bow and dm-default-key) to use the new way of specifying inline crypto passthrough support (DM_TARGET_PASSES_CRYPTO) rather than the old way (may_passthrough_inline_crypto). These changes should be folded into: ANDROID-dm-bow-Add-dm-bow-feature.patch ANDROID-dm-add-dm-default-key-target-for-metadata-encryption.patch Test: tested on db845c; verified that inline crypto support gets passed through over dm-linear.

bfq-iosched: Revert "bfq: Fix computation of shallow depth"
[ Upstream commit 388c705b95f23f317fa43e6abf9ff07b583b721a ]
This reverts commit 6d4d273588378c65915acaf7b2ee74e9dd9c130a.
bfq.limit_depth passes word_depths[] as shallow_depth down to sbitmap core
sbitmap_get_shallow, which uses just the number to limit the scan depth of
each bitmap word, formula:
scan_percentage_for_each_word = shallow_depth / (1 << sbimap->shift) * 100%
That means the comments's percentiles 50%, 75%, 18%, 37% of bfq are correct.
But after commit patch 'bfq: Fix computation of shallow depth', we use
sbitmap.depth instead, as a example in following case:
sbitmap.depth = 256, map_nr = 4, shift = 6; sbitmap_word.depth = 64.
The resulsts of computed bfqd->word_depths[] are {128, 192, 48, 96}, and
three of the numbers exceed core dirver's 'sbitmap_word.depth=64' limit
nothing.

blk-cgroup: Use cond_resched() when destroy blkgs
[ Upstream commit 6c635caef410aa757befbd8857c1eadde5cc22ed ] On !PREEMPT kernel, we can get below softlockup when doing stress testing with creating and destroying block cgroup repeatly. The reason is it may take a long time to acquire the queue's lock in the loop of blkcg_destroy_blkgs(), or the system can accumulate a huge number of blkgs in pathological cases. We can add a need_resched() check on each loop and release locks and do cond_resched() if true to avoid this issue, since the blkcg_destroy_blkgs() is not called from atomic contexts.

blk-mq: test QUEUE_FLAG_HCTX_ACTIVE for sbitmap_shared in hctx_may_queue
commit 2569063c7140c65a0d0ad075e95ddfbcda9ba3c0 upstream.
In case of blk_mq_is_sbitmap_shared(), we should test QUEUE_FLAG_HCTX_ACTIVE against
q->queue_flags instead of BLK_MQ_S_TAG_ACTIVE.
So fix it.

FROMLIST: block: bsg: resume platform device before accessing
It may happen that the underlying device's runtime-pm is not controlled by block-pm. So it's possible that when commands are sent to the device, it's suspended and may not be resumed by blk-pm. Hence explicitly resume the parent which is the platform device.

blk-mq-debugfs: Add decode for BLK_MQ_F_TAG_HCTX_SHARED
[ Upstream commit 02f938e9fed1681791605ca8b96c2d9da9355f6a ]
Showing the hctx flags for when BLK_MQ_F_TAG_HCTX_SHARED is set gives
something like:
root@debian:/home/john# more /sys/kernel/debug/block/sda/hctx0/flags
alloc_policy=FIFO SHOULD_MERGE|TAG_QUEUE_SHARED|3
Add the decoding for that flag.
Fixes:

bfq: Fix computation of shallow depth
[ Upstream commit 6d4d273588378c65915acaf7b2ee74e9dd9c130a ] BFQ computes number of tags it allows to be allocated for each request type based on tag bitmap. However it uses 1 << bitmap.shift as number of available tags which is wrong. 'shift' is just an internal bitmap value containing logarithm of how many bits bitmap uses in each bitmap word. Thus number of tags allowed for some request types can be far to low. Use proper bitmap.depth which has the number of tags instead.

blk-iocost: fix NULL iocg deref from racing against initialization
commit d16baa3f1453c14d680c5fee01cd122a22d0e0ce upstream. When initializing iocost for a queue, its rqos should be registered before the blkcg policy is activated to allow policy data initiailization to lookup the associated ioc. This unfortunately means that the rqos methods can be called on bios before iocgs are attached to all existing blkgs. While the race is theoretically possible on ioc_rqos_throttle(), it mostly happened in ioc_rqos_merge() due to the difference in how they lookup ioc. The former determines it from the passed in @rqos and then bails before dereferencing iocg if the looked up ioc is disabled, which most likely is the case if initialization is still in progress. The latter looked up ioc by dereferencing the possibly NULL iocg making it a lot more prone to actually triggering the bug. * Make ioc_rqos_merge() use the same method as ioc_rqos_throttle() to look up ioc for consistency. * Make ioc_rqos_throttle() and ioc_rqos_merge() test for NULL iocg before dereferencing it. * Explain the danger of NULL iocgs in blk_iocost_init().

scsi: block: Do not accept any requests while suspended
[ Upstream commit 52abca64fd9410ea6c9a3a74eab25663b403d7da ] blk_queue_enter() accepts BLK_MQ_REQ_PM requests independent of the runtime power management state. Now that SCSI domain validation no longer depends on this behavior, modify the behavior of blk_queue_enter() as follows: - Do not accept any requests while suspended. - Only process power management requests while suspending or resuming. Submitting BLK_MQ_REQ_PM requests to a device that is runtime suspended causes runtime-suspended devices not to resume as they should. The request which should cause a runtime resume instead gets issued directly, without resuming the device first. Of course the device can't handle it properly, the I/O fails, and the device remains suspended. The problem is fixed by checking that the queue's runtime-PM status isn't RPM_SUSPENDED before allowing a request to be issued, and queuing a runtime-resume request if it is. In particular, the inline blk_pm_request_resume() routine is renamed blk_pm_resume_queue() and the code is unified by merging the surrounding checks into the routine. If the queue isn't set up for runtime PM, or there currently is no restriction on allowed requests, the request is allowed. Likewise if the BLK_MQ_REQ_PM flag is set and the status isn't RPM_SUSPENDED. Otherwise a runtime resume is queued and the request is blocked until conditions are more suitable.

scsi: block: Fix a race in the runtime power management code
commit fa4d0f1992a96f6d7c988ef423e3127e613f6ac9 upstream.
With the current implementation the following race can happen:
* blk_pre_runtime_suspend() calls blk_freeze_queue_start() and
blk_mq_unfreeze_queue().
* blk_queue_enter() calls blk_queue_pm_only() and that function returns
true.
* blk_queue_enter() calls blk_pm_request_resume() and that function does
not call pm_request_resume() because the queue runtime status is
RPM_ACTIVE.
* blk_pre_runtime_suspend() changes the queue status into RPM_SUSPENDING.
Fix this race by changing the queue runtime status into RPM_SUSPENDING
before switching q_usage_counter to atomic mode.

block/keyslot-manager: prevent crash when num_slots=1
If there is only one keyslot, then blk_ksm_init() computes
slot_hashtable_size=1 and log_slot_ht_size=0. This causes
blk_ksm_find_keyslot() to crash later because it uses
hash_ptr(key, log_slot_ht_size) to find the hash bucket containing the
key, and hash_ptr() doesn't support the bits == 0 case.
Fix this by making the hash table always have at least 2 buckets.
Tested by running:
kvm-xfstests -c ext4 -g encrypt -m inlinecrypt \
-o blk-crypto-fallback.num_keyslots=1

block: mark flush request as IDLE when it is really finished
For avoiding use-after-free on flush request, we call its .end_io() from
both timeout code path and __blk_mq_end_request().
When flush request's ref doesn't drop to zero, it is still used, we
can't mark it as IDLE, so fix it by marking IDLE when its refcount drops
to zero really.

blk-mq: mark flush request as IDLE in flush_end_io()
Mark flush request as IDLE in its .end_io(), aligning it with how normal requests behave. The flush request stays in in-flight tags if we're not using an IO scheduler, so we need to change its state into IDLE. Otherwise, we will hang in blk_mq_tagset_wait_completed_request() during error recovery because flush the request state is kept as COMPLETED.

block: advance iov_iter on bio_add_hw_page failure
When the bio's size reaches max_append_sectors, bio_add_hw_page returns
0 then __bio_iov_append_get_pages returns -EINVAL. This is an expected
result of building a small enough bio not to be split in the IO path.
However, iov_iter is not advanced in this case, causing the same pages
are filled for the bio again and again.
Fix the case by properly advancing the iov_iter for already processed
pages.

blk-mq: remove the calling of local_memory_node()
We don't need to check whether the node is memoryless numa node before calling allocator interface. SLUB(and SLAB,SLOB) relies on the page allocator to pick a node. Page allocator should deal with memoryless nodes just fine. It has zonelists constructed for each possible nodes. And it will automatically fall back into a node which is closest to the requested node. As long as __GFP_THISNODE is not enforced of course. The code comments of kmem_cache_alloc_node() of SLAB also showed this: * Fallback to other node is possible if __GFP_THISNODE is not set. blk-mq code doesn't set __GFP_THISNODE, so we can remove the calling of local_memory_node().

Using "@bio's parent" causes the following waring: ./block/bio.c:10: WARNING: Inline emphasis start-string without end-string. The main problem here is that this would be converted into: **bio**'s parent By kernel-doc, which is not a valid notation. It would be possible to use, instead, this kernel-doc markup: ``bio's`` parent Yet, here, is probably simpler to just use an altenative language: the parent of @bio Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> |

block: add zone specific block statuses
A zoned device with limited resources to open or activate zones may return an error when the host exceeds those limits. The same command may be successful if retried later, but the host needs to wait for specific zone states before it should expect a retry to succeed. Have the block layer provide an appropriate status for these conditions so applications can distinuguish this error for special handling.

dm: fix request-based DM to not bounce through indirect dm_submit_bio
It is unnecessary to force request-based DM to call into bio-based
dm_submit_bio (via indirect disk->fops->submit_bio) only to have it then
call blk_mq_submit_bio().
Fix this by establishing a request-based DM block_device_operations
(dm_rq_blk_dops, which doesn't have .submit_bio) and update
dm_setup_md_queue() to set md->disk->fops to it for
DM_TYPE_REQUEST_BASED.
Remove DM_TYPE_REQUEST_BASED conditional in dm_submit_bio and unexport
blk_mq_submit_bio.

block: Consider only dispatched requests for inflight statistic
According to Documentation/block/stat.rst, inflight should not include
I/O requests that are in the queue but not yet dispatched to the device,
but blk-mq identifies as inflight any request that has a tag allocated,
which, for queues without elevator, happens at request allocation time
and before it is queued in the ctx (default case in blk_mq_submit_bio).
In addition, current behavior is different for queues with elevator from
queues without it, since for the former the driver tag is allocated at
dispatch time. A more precise approach would be to only consider
requests with state MQ_RQ_IN_FLIGHT.
This effectively reverts commit

block: warn if !__GFP_DIRECT_RECLAIM in bio_crypt_set_ctx()
bio_crypt_set_ctx() assumes its gfp_mask argument always includes __GFP_DIRECT_RECLAIM, so that the mempool_alloc() will always succeed. For now this assumption is still fine, since no callers violate it. Making bio_crypt_set_ctx() able to fail would add unneeded complexity. However, if a caller didn't use __GFP_DIRECT_RECLAIM, it would be very hard to notice the bug. Make it easier by adding a WARN_ON_ONCE().

blk-mq: call commit_rqs while list empty but error happen
Blk-mq should call commit_rqs once 'bd.last != true' and no more
request will come(so virtscsi can kick the virtqueue, e.g.). We already
do that in 'blk_mq_dispatch_rq_list/blk_mq_try_issue_list_directly' while
list not empty and 'queued > 0'. However, we can seen the same scene
once the last request in list call queue_rq and return error like
BLK_STS_IOERR which will not requeue the request, and lead that list
empty but need call commit_rqs too(Or the request for virtscsi will stay
timeout until other request kick virtqueue).
We found this problem by do fsstress test with offline/online virtscsi
device repeat quickly.

blk-mq: add cond_resched() in __blk_mq_alloc_rq_maps()
We found blk_mq_alloc_rq_maps() takes more time in kernel space when
testing nvme device hot-plugging. The test and anlysis as below.
Debug code,
1, blk_mq_alloc_rq_maps():
u64 start, end;
depth = set->queue_depth;
start = ktime_get_ns();
pr_err("[%d:%s switch:%ld,%ld] queue depth %d, nr_hw_queues %d\n",
current->pid, current->comm, current->nvcsw, current->nivcsw,
set->queue_depth, set->nr_hw_queues);
do {
err = __blk_mq_alloc_rq_maps(set);
if (!err)
break;
set->queue_depth >>= 1;
if (set->queue_depth < set->reserved_tags + BLK_MQ_TAG_MIN) {
err = -ENOMEM;
break;
}
} while (set->queue_depth);
end = ktime_get_ns();
pr_err("[%d:%s switch:%ld,%ld] all hw queues init cost time %lld ns\n",
current->pid, current->comm,
current->nvcsw, current->nivcsw, end - start);
2, __blk_mq_alloc_rq_maps():
u64 start, end;
for (i = 0; i < set->nr_hw_queues; i++) {
start = ktime_get_ns();
if (!__blk_mq_alloc_rq_map(set, i))
goto out_unwind;
end = ktime_get_ns();
pr_err("hw queue %d init cost time %lld ns\n", i, end - start);
}
Test nvme hot-plugging with above debug code, we found it totally cost more
than 3ms in kernel space without being scheduled out when alloc rqs for all
16 hw queues with depth 1023, each hw queue cost about 140-250us. The cost
time will be increased with hw queue number and queue depth increasing. And
in an extreme case, if __blk_mq_alloc_rq_maps() returns -ENOMEM, it will try
"queue_depth >>= 1", more time will be consumed.

iocost: consider iocgs with active delays for debt forgiveness
An iocg may have 0 debt but non-zero delay. The current debt forgiveness logic doesn't act on such iocgs. This can lead to unexpected behaviors - an iocg with a little bit of debt will have its delay canceled through debt forgiveness but one w/o any debt but active delay will have to wait out until its delay decays out. This patch updates the debt handling logic so that it treats delays the same as debts. If either debt or delay is active, debt forgiveness logic kicks in and acts on both the same way. Also, avoid turning the debt and delay directly to zero as that can confuse state transitions. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jens Axboe <axboe@kernel.dk> |

iocost: reimplement debt forgiveness using average usage
Debt forgiveness logic was counting the number of consecutive !busy periods as the trigger condition. While this usually works, it can easily be thrown off by temporary fluctuations especially on configurations w/ short periods. This patch reimplements debt forgiveness so that: * Use the average usage over the forgiveness period instead of counting consecutive periods. * Debt is reduced at around the target rate (1/2 every 100ms) regardless of ioc period duration. * Usage threshold is raised to 50%. Combined with the preceding changes and the switch to average usage, this makes debt forgivness a lot more effective at reducing the amount of unnecessary idleness. * Constants are renamed with DFGV_ prefix.

iocost: recalculate delay after debt reduction
Debt sets the initial delay duration which is decayed over time. The current debt reduction halved the debt but didn't change the delay. It prevented future debts from increasing delay but didn't do anything to lower the existing delay, limiting the mechanism's ability to reduce unnecessary idling. Reset iocg->delay to 0 after debt reduction so that iocg_kick_waitq() recalculates new delay value based on the reduced debt amount.

iocost: replace nr_shortages cond in ioc_forgive_debts() with busy_level one
Debt reduction was blocked if any iocg was short on budget in the past period to avoid reducing debts while some iocgs are saturated. However, this ends up unnecessarily blocking debt reduction due to temporary local imbalances when the device is generally being underutilized, while also failing to block when the underlying device is overwhelmed and the usage becomes low from high latency. Given that debt accumulation mostly happens with swapout bursts which can significantly deteriorate the underlying device's latency response, the current logic is not great. Let's replace it with ioc->busy_level based condition so that we block debt reduction when the underlying device is being saturated. ioc_forgive_debts() call is moved after busy_level determination.

bdi: replace BDI_CAP_STABLE_WRITES with a queue and a sb flag
The BDI_CAP_STABLE_WRITES is one of the few bits of information in the backing_dev_info shared between the block drivers and the writeback code. To help untangling the dependency replace it with a queue flag and a superblock flag derived from it. This also helps with the case of e.g. a file system requiring stable writes due to its own checksumming, but not forcing it on other users of the block device like the swap code. One downside is that we an't support the stable_pages_required bdi attribute in sysfs anymore. It is replaced with a queue attribute which also is writable for easier testing.

block: lift setting the readahead size into the block layer
Drivers shouldn't really mess with the readahead size, as that is a VM concept. Instead set it based on the optimal I/O size by lifting the algorithm from the md driver when registering the disk. Also set bdi->io_pages there as well by applying the same scheme based on max_sectors. To ensure the limits work well for stacking drivers a new helper is added to update the readahead limits from the block limits, which is also called from disk_stack_limits.

block: allow 'chunk_sectors' to be non-power-of-2
It is possible, albeit more unlikely, for a block device to have a non power-of-2 for chunk_sectors (e.g. 10+2 RAID6 with 128K chunk_sectors, which results in a full-stripe size of 1280K. This causes the RAID6's io_opt to be advertised as 1280K, and a stacked device _could_ then be made to use a blocksize, aka chunk_sectors, that matches non power-of-2 io_opt of underlying RAID6 -- resulting in stacked device's chunk_sectors being a non power-of-2).

scsi: sd: sd_zbc: Fix handling of host-aware ZBC disks
When CONFIG_BLK_DEV_ZONED is disabled, allow using host-aware ZBC disks as
regular disks. In this case, ensure that command completion is correctly
executed by changing sd_zbc_complete() to return good_bytes instead of 0
and causing a hang during device probe (endless retries).
When CONFIG_BLK_DEV_ZONED is enabled and a host-aware disk is detected to
have partitions, it will be used as a regular disk. In this case, make sure
to not do anything in sd_zbc_revalidate_zones() as that triggers warnings.
Since all these different cases result in subtle settings of the disk queue
zoned model, introduce the block layer helper function
blk_queue_set_zoned() to generically implement setting up the effective
zoned model according to the disk type, the presence of partitions on the
disk and CONFIG_BLK_DEV_ZONED configuration.

iocost: fix infinite loop bug in adjust_inuse_and_calc_cost()
adjust_inuse_and_calc_cost() is responsible for reducing the amount of
donated weights dynamically in period as the budget runs low. Because we
don't want to do full donation calculation in period, we keep latching up
inuse by INUSE_ADJ_STEP_PCT of the active weight of the cgroup until the
resulting hweight_inuse is satisfactory.
Unfortunately, the adj_step calculation was reading the active weight before
acquiring ioc->lock. Because the current thread could have lost race to
activate the iocg to another thread before entering this function, it may
read the active weight as zero before acquiring ioc->lock. When this
happens, the adj_step is calculated as zero and the incremental adjustment
loop becomes an infinite one.
Fix it by fetching the active weight after acquiring ioc->lock.

blk-mq: always allow reserved allocation in hctx_may_queue
NVMe shares tagset between fabric queue and admin queue or between connect_q and NS queue, so hctx_may_queue() can be called to allocate request for these queues. Tags can be reserved in these tagset. Before error recovery, there is often lots of in-flight requests which can't be completed, and new reserved request may be needed in error recovery path. However, hctx_may_queue() can always return false because there is too many in-flight requests which can't be completed during error handling. Finally, nothing can proceed. Fix this issue by always allowing reserved tag allocation in hctx_may_queue(). This is reasonable because reserved tags are supposed to always be available.

blkcg: add plugging support for punt bio
The test and the explaination of the patch as bellow.
Before test we added more debug code in blkg_async_bio_workfn():
int count = 0
if (bios.head && bios.head->bi_next) {
need_plug = true;
blk_start_plug(&plug);
}
while ((bio = bio_list_pop(&bios))) {
/*io_punt is a sysctl user interface to control the print*/
if(io_punt) {
printk("[%s:%d] bio start,size:%llu,%d count=%d plug?%d\n",
current->comm, current->pid, bio->bi_iter.bi_sector,
(bio->bi_iter.bi_size)>>9, count++, need_plug);
}
submit_bio(bio);
}
if (need_plug)
blk_finish_plug(&plug);
Steps that need to be set to trigger *PUNT* io before testing:
mount -t btrfs -o compress=lzo /dev/sda6 /btrfs
mount -t cgroup2 nodev /cgroup2
mkdir /cgroup2/cg3
echo "+io" > /cgroup2/cgroup.subtree_control
echo "8:0 wbps=1048576000" > /cgroup2/cg3/io.max #1000M/s
echo $$ > /cgroup2/cg3/cgroup.procs
Then use dd command to test btrfs PUNT io in current shell:
dd if=/dev/zero of=/btrfs/file bs=64K count=100000
Test hardware environment as below:
[root@localhost btrfs]# lscpu

Analysis of above 3 test results with different system load:
>From above test, we can see more and more continuous bios can be plugged
with system load increasing. When run "stress -c 64 &", 310 continuous
bios are plugged; When run "stress -c 32 &", 260 continuous bios are
plugged; When don't run stress, at most only 2 continuous bios are
plugged, in most cases, bio_list only contains one single bio.
How to explain above phenomenon:
We know, in submit_bio(), if the bio is a REQ_CGROUP_PUNT io, it will
queue a work to workqueue blkcg_punt_bio_wq. But when the workqueue is
scheduled, it depends on the system load. When system load is low, the
workqueue will be quickly scheduled, and the bio in bio_list will be
quickly processed in blkg_async_bio_workfn(), so there is less chance
that the same io submit thread can add multiple continuous bios to
bio_list before workqueue is scheduled to run. The analysis aligned with
above test "3".
When system load is high, there is some delay before the workqueue can
be scheduled to run, the higher the system load the greater the delay.
So there is more chance that the same io submit thread can add multiple
continuous bios to bio_list. Then when the workqueue is scheduled to run,
there are more continuous bios in bio_list, which will be processed in
blkg_async_bio_workfn(). The analysis aligned with above test "1" and "2".
According to test, we can get io performance improved with the patch,
especially when system load is higher. Another optimazition is to use
the plug only when bio_list contains at least 2 bios.

blk-mq, elevator: Count requests per hctx to improve performance
High CPU utilization on "native_queued_spin_lock_slowpath" due to lock contention is possible for mq-deadline and bfq IO schedulers when nr_hw_queues is more than one. It is because kblockd work queue can submit IO from all online CPUs (through blk_mq_run_hw_queues()) even though only one hctx has pending commands. The elevator callback .has_work for mq-deadline and bfq scheduler considers pending work if there are any IOs on request queue but it does not account hctx context. Add a per-hctx 'elevator_queued' count to the hctx to avoid triggering the elevator even though there are no requests queued.

blk-mq: Record nr_active_requests per queue for when using shared sbitmap
The per-hctx nr_active value can no longer be used to fairly assign a share of tag depth per request queue for when using a shared sbitmap, as it does not consider that the tags are shared tags over all hctx's. For this case, record the nr_active_requests per request_queue, and make the judgement based on that value.

blk-mq: Facilitate a shared sbitmap per tagset
Some SCSI HBAs (such as HPSA, megaraid, mpt3sas, hisi_sas_v3 ..) support multiple reply queues with single hostwide tags. In addition, these drivers want to use interrupt assignment in pci_alloc_irq_vectors(PCI_IRQ_AFFINITY). However, as discussed in [0], CPU hotplug may cause in-flight IO completion to not be serviced when an interrupt is shutdown. That problem is solved in commit |

blk-mq: Free tags in blk_mq_init_tags() upon error
Since the tags are allocated in blk_mq_init_tags(), it's better practice to free in that same function upon error, rather than a callee which is to init the bitmap tags (blk_mq_init_tags()).

blk-iocost: implement vtime loss compensation
When an iocg accumulates too much vtime or gets deactivated, we throw away some vtime, which lowers the overall device utilization. As the exact amount which is being thrown away is known, we can compensate by accelerating the vrate accordingly so that the extra vtime generated in the current period matches what got lost. This significantly improves work conservation when involving high weight cgroups with intermittent and bursty IO patterns.

blk-iocost: halve debts if device stays idle
A low weight iocg can amass a large amount of debt, for example, when anonymous memory gets reclaimed aggressively. If the system has a lot of memory paired with a slow IO device, the debt can span multiple seconds or more. If there are no other subsequent IO issuers, the in-debt iocg may end up blocked paying its debt while the IO device is idle. This patch implements a mechanism to protect against such pathological cases. If the device has been sufficiently idle for a substantial amount of time, the debts are halved. The criteria are on the conservative side as we want to resolve the rare extreme cases without impacting regular operation by forgiving debts too readily.

blk-iocost: revamp debt handling
Debt handling had several issues. * How much inuse a debtor carries wasn't clearly defined. inuse would be driven down over time from not issuing IOs but it'd be better to clamp it to minimum immediately once in debt. * How much can be paid off was determined by hweight_inuse. As inuse was driven down, the payment amount would fall together regardless of the debtor's active weight. This means that the debtors were punished harshly. * ioc_rqos_merge() wasn't calling blkcg_schedule_throttle() after iocg_kick_delay(). This patch revamps debt handling so that * Debt handling owns inuse for iocgs in debt and keeps them at zero. * Payment amount is determined by hweight_active. This is more deterministic and safer than hweight_inuse but still far from ideal in that it doesn't factor in possible donations from other iocgs for debt payments. This likely needs further improvements in the future. * iocg_rqos_merge() now calls blkcg_schedule_throttle() as necessary.

blk-iocost: add absolute usage stat
Currently, iocost doesn't collect or expose any statistics punting off all monitoring duties to drgn based iocost_monitor.py. While it works for some scenarios, there are some usability and data availability challenges. For example, accurate per-cgroup usage information can't be tracked by vtime progression at all and the number available in iocg->usages[] are really short-term snapshots used for control heuristics with possibly significant errors. This patch implements per-cgroup absolute usage stat counter and exposes it through io.stat along with the current vrate. Usage stat collection and flushing employ the same method as cgroup rstat on the active iocg's and the only hot path overhead is preemption toggling and adding to a percpu counter.

blk-iocost: implement delay adjustment hysteresis
Curently, iocost syncs the delay duration to the outstanding debt amount, which seemed enough to protect the system from anon memory hogs. However, that was mostly because the delay calcuation was using hweight_inuse which quickly converges towards zero under debt for delay duration calculation, often pusnishing debtors overly harshly for longer than deserved. The previous patch fixed the delay calcuation and now the protection against anonymous memory hogs isn't enough because the effect of delay is indirect and non-linear and a huge amount of future debt can accumulate abruptly while unthrottled. This patch implements delay hysteresis so that delay is decayed exponentially over time instead of getting cleared immediately as debt is paid off. While the overall behavior is similar to the blk-cgroup implementation used by blk-iolatency, a lot of the details are different and due to the empirical nature of the mechanism, it's challenging to adapt the mechanism for one controller without negatively impacting the other. As the delay is gradually decayed now, there's no point in running it from its own hrtimer. Periodic updates are now performed from ioc_timer_fn() and the dedicated hrtimer is removed.

blk-iocost: revamp in-period donation snapbacks
When the margin drops below the minimum on a donating iocg, donation is immediately canceled in full. There are a couple shortcomings with the current behavior. * It's abrupt. A small temporary budget deficit can lead to a wide swing in weight allocation and a large surplus. * It's open coded in the issue path but not implemented for the merge path. A series of merges at a low inuse can make the iocg incur debts and stall incorrectly. This patch reimplements in-period donation snapbacks so that * inuse adjustment and cost calculations are factored into adjust_inuse_and_calc_cost() which is called from both the issue and merge paths. * Snapbacks are more gradual. It occurs in quarter steps. * A snapback triggers if the margin goes below the low threshold and is lower than the budget at the time of the last adjustment. * For the above, __propagate_weights() stores the margin in iocg->saved_margin. Move iocg->last_inuse storing together into __propagate_weights() for consistency. * Full snapback is guaranteed when there are waiters. * With precise donation and gradual snapbacks, inuse adjustments are now a lot more effective and the value of scaling inuse on weight changes isn't clear.

blk-iocost: grab ioc->lock for debt handling
Currently, debt handling requires only iocg->waitq.lock. In the future, we want to adjust and propagate inuse changes depending on debt status. Let's grab ioc->lock in debt handling paths in preparation. * Because ioc->lock nests outside iocg->waitq.lock, the decision to grab ioc->lock needs to be made before entering the critical sections. * Add and use iocg_[un]lock() which handles the conditional double locking. * Add @pay_debt to iocg_kick_waitq() so that debt payment happens only when the caller grabbed both locks.

blk-iocost: revamp donation amount determination
iocost has various safety nets to combat inuse adjustment calculation inaccuracies. With Andy's method implemented in transfer_surpluses(), inuse adjustment calculations are now accurate and we can make donation amount determinations accurate too. * Stop keeping track of past usage history and using the maximum. Act on the immediate usage information. * Remove donation constraints defined by SURPLUS_* constants. Donate whatever isn't used. * Determine the donation amount so that the iocg will end up with MARGIN_TARGET_PCT budget at the end of the coming period assuming the same usage as the previous period. TARGET is set at 50% of period, which is the previous maximum. This provides smooth convergence for most repetitive IO patterns. * Apply donation logic early at 20% budget. There's no risk in doing so as the calculation is based on the delta between the current budget and the target budget at the end of the coming period. * Remove preemptive iocg activation for zero cost IOs. As donation can reach near zero now, the mere activation doesn't provide any protection anymore. In the unlikely case that this becomes a problem, the right solution is assigning appropriate costs for such IOs. This significantly improves the donation determination logic while also simplifying it. Now all donations are immediate, exact and smooth.

blk-iocost: streamline vtime margin and timer slack handling
The margin handling was pretty inconsistent.
* ioc->margin_us and ioc->inuse_margin_vtime were used as vtime margin
thresholds. However, the two are in different units with the former
requiring conversion to vtime on use.
* iocg_kick_waitq() was using a quarter of WAITQ_TIMER_MARGIN_PCT of
period_us as the timer slack - ~1.2%. While iocg_kick_delay() was using a
quarter of ioc->margin_us - ~12.5%. There aren't strong reasons to use
different values for the two.
This patch cleans up margin and timer slack handling:
* vtime margins are now recorded in ioc->margins.{min, max} on period
duration changes and used consistently.
* Timer slack is now 1% of period_us and recorded in ioc->timer_slack_ns and
used consistently for iocg_kick_waitq() and iocg_kick_delay().
The only functional change is shortening of timer slack. No meaningful
visible change is expected.

blk-iocost: implement Andy's method for donation weight updates
iocost implements work conservation by reducing iocg->inuse and propagating the adjustment upwards proportionally. However, while I knew the target absolute hierarchical proportion - adjusted hweight_inuse, I couldn't figure out how to determine the iocg->inuse adjustment to achieve that and approximated the adjustment by scaling iocg->inuse using the proportion of the needed hweight_inuse changes. When nested, these scalings aren't accurate even when adjusting a single node as the donating node also receives the benefit of the donated portion. When multiple nodes are donating as they often do, they can be wildly wrong. iocost employed various safety nets to combat the inaccuracies. There are ample buffers in determining how much to donate, the adjustments are conservative and gradual. While it can achieve a reasonable level of work conservation in simple scenarios, the inaccuracies can easily add up leading to significant loss of total work. This in turn makes it difficult to closely cap vrate as vrate adjustment is needed to compensate for the loss of work. The combination of inaccurate donation calculations and vrate adjustments can lead to wide fluctuations and clunky overall behaviors. Andy Newell devised a method to calculate the needed ->inuse updates to achieve the target hweight_inuse's. The method is compatible with the proportional inuse adjustment propagation which allows all hot path operations to be local to each iocg. To roughly summarize, Andy's method divides the tree into donating and non-donating parts, calculates global donation rate which is used to determine the target hweight_inuse for each node, and then derives per-level proportions. There's non-trivial amount of math involved.
