Merge tag 'xfs-5.16-fixes-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs fix from Darrick Wong:
"This fixes a race between a readonly remount process and other
processes that hold a file IOLOCK on files that previously experienced
copy on write, that could result in severe filesystem corruption if
the filesystem is then remounted rw.
I think this is fairly rare (since the only reliable reproducer I have
that fits the second criteria is the experimental xfs_scrub program),
but the race is clear, so we still need to fix this.
Summary:
- Fix a data corruption vector that can result from the ro remount
process failing to clear all speculative preallocations from files
and the rw remount process not noticing the incomplete cleanup"
