extracting the work from its queue. In addition, this processing also
decrement the inode's i_count. If there are any remaining works in queue
before this process terminates, we have unbalanced increment and decrement
of i_count. Thus it can cause assertion failure of vn_count. The fix
allows xyssyncd to process any remaining work before it is shutdown.

xfs_iomap_t if the block at the specified offset fits into it, or a NULL
pointer otherwise. This patch passed the full 64bit offset into the inode
that all callers have anyway, and changes the return value to a simple
boolean. Also the function gets a more descriptive name: xfs_iomap_valid.

allows us to submit much larger I/Os instead of sending down lots of small
buffer_heads. To do this we need to have a rather complicated I/O
submission and completion tracking infrastructure. Part of the latter has
been merged already a long time ago for direct I/O support. Part of the
problem is that we need to track sub-pagesize regions and for that we
still need buffer_heads for the time beeing. Long-term I hope we can move
to better data strucutures and/or maybe move this to fs/mpage.c instead of
having it in XFS. Original patch from Nathan Scott with various updates
from David Chinner and Christoph Hellwig.

was caused by ENOSPC but not Rreclaimed by xfs_release or xfs_inactive.
The fix changed the condition in xfs_release and xfs_inactive to invoke
xfs_inactive_free_eofblocks for this special case, changed
xfs_inactive_free_eofblocks to clean the delayed blks after eof. It also
changed xfs_write to set correct eof when ENOSPC occurs.

Modify the initial trace output (which is based on flags in the binary
header) so that it is not done until after the magic number check. This
may well not be a flat format binary, so the flags could be invalid.
