We already have the helper, we can convert the rest of the kernel
mechanically using:
git grep -l 'atomic_inc_not_zero.*mm_users' | xargs sed -i 's/atomic_inc_not_zero(&\(.*\)->mm_users)/mmget_not_zero\(\1\)/'
This is needed for a later patch that hooks into the helper, but might
be a worthwhile cleanup on its own.

if (epds.events & EPOLLEXCLUSIVE) {

if (op == EPOLL_CTL_ADD && (is_file_epoll(tf.file) ||

Currently all the p_paddr of PT_LOAD headers are assigned to 0, which is
not true and could be misleading, since 0 is a valid physical address.
User space tools like makedumpfile needs to know physical address for
PT_LOAD segments of direct mapped regions. Therefore this patch updates
paddr for such regions. It also sets an invalid paddr (-1) for other
regions, so that user space tool can know whether a physical address
provided in PT_LOAD is correct or not.
I do not know why it was 0, which is a valid physical address. But
certainly, it might break some user space tools, and those need to be
fixed. For example, see following code from kexec-tools
kexec/kexec-elf.c:build_mem_phdrs()
if ((phdr->p_paddr + phdr->p_memsz) < phdr->p_paddr) {
/* The memory address wraps */
if (probe_debug) {
fprintf(stderr, "ELF address wrap around\n");
}
return -1;
}
We do not need to perform above check for an invalid physical address.
I think, kexec-tools and makedumpfile will need fixup. I already have
those fixup which will be sent upstream once this patch makes through.
Pro with this approach is that, it will help to calculate variable like
page_offset, phys_base from PT_LOAD even when they are randomized and
therefore will reduce many variable and version specific values in user
space tools.
Having an ASLR offset information can help to translate an identity
mapped virtual address to a physical address. But that would be an
additional field in PT_LOAD header structure and an arch dependent
value.
Moreover, sending a valid physical address like 0 does not seem right.
So, IMHO it is better to fix that and send valid physical address when
available (identity mapped).

GUI environments seem to be becoming more agressive at scanning
filesystems, to the point where autofs cannot expire mounts at all.
This is one key reason the update of the autofs dentry info last_used
field is done in the expire system when the dentry is seen to be in use.
But somewhere along the way instances of the update has crept back into
the autofs path walk functions which, with the more aggressive file
access patterns, is preventing expiration.
Changing the update in the path walk functions allows autofs to at least
make progress in spite of frequent immediate re-mounts from file
accesses.

The introduction of the multi-device feature partially broke the support
for zoned block devices. In the function f2fs_scan_devices, sbi->devs
allocation and initialization is skipped in the case of a single device
mount. This result in no device information structure being allocated
for the device. This is fine if the device is a regular device, but in
the case of a zoned block device, the device zone type array is not
initialized, which causes the function __f2fs_issue_discard_zone to fail
as get_blkz_type is unable to determine the zone type of a section.
Fix this by always allocating and initializing the sbi->devs device
information array even in the case of a single device if that device is
zoned. For this particular case, make sure to obtain a reference on the
single device so that the call to blkdev_put() in destroy_device_list
operates as expected.

In scenario of intensively node allocation, free nids will be ran out
soon, then it needs to stop to load free nids by traversing NAT blocks,
in worse case, if NAT blocks does not be cached in memory, it generates
IOs which slows down our foreground operations.
In order to speed up node allocation, in this patch we introduce a new
free_nid_bitmap array, so there is an bitmap table for each NAT block,
Once the NAT block is loaded, related bitmap cache will be switched on,
and bitmap will be set during traversing nat entries in NAT block, later
we can query and update nid usage status in memory completely.
With such implementation, I expect performance of node allocation can be
improved in the long-term after filesystem image is mounted.

This patches adds bitmaps to represent empty or full NAT blocks containing
free nid entries.
If we can find valid crc|cp_ver in the last block of checkpoint pack, we'll
use these bitmaps when building free nids. In order to avoid checkpointing
burden, up-to-date bitmaps will be flushed only during umount time. So,
normally we can get this gain, but when power-cut happens, we rely on fsck.f2fs
which recovers this bitmap again.
After this patch, we build free nids from nid #0 at mount time to make more
full NAT blocks, but in runtime, we check empty NAT blocks to load free nids
without loading any NAT pages from disk.
