Merge tag 'xfs-5.5-merge-16' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull XFS updates from Darrick Wong:
"For this release, we changed quite a few things.
Highlights:
- Fixed some long tail latency problems in the block allocator
- Removed some long deprecated (and for the past several years no-op)
mount options and ioctls
- Strengthened the extended attribute and directory verifiers
- Audited and fixed all the places where we could return EFSCORRUPTED
without logging anything
- Refactored the old SGI space allocation ioctls to make the
equivalent fallocate calls
- Fixed a race between fallocate and directio
- Fixed an integer overflow when files have more than a few
billion(!) extents
- Fixed a longstanding bug where quota accounting could be incorrect
when performing unwritten extent conversion on a freshly mounted fs
- Fixed various complaints in scrub about soft lockups and
unresponsiveness to signals
- De-vtable'd the directory handling code, which should make it
faster
- Converted to the new mount api, for better or for worse
- Cleaned up some memory leaks
and quite a lot of other smaller fixes and cleanups.
A more detailed summary:
- Fill out the build string
- Prevent inode fork extent count overflows
- Refactor the allocator to reduce long tail latency
- Rework incore log locking a little to reduce spinning

parts
