Merge tag 'xfs-5.13-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull more xfs updates from Darrick Wong:
"Except for the timestamp struct renaming patches, everything else in
here are bug fixes:
- Rename the log timestamp struct.
- Remove broken transaction counter debugging that wasn't working
correctly on very old filesystems.
- Various fixes to make pre-lazysbcount filesystems work properly
again.
- Fix a free space accounting problem where we neglected to consider
free space btree blocks that track metadata reservation space when
deciding whether or not to allow caller to reserve space for a
metadata update.
- Fix incorrect pagecache clearing behavior during FUNSHARE ops.
- Don't allow log writes if the data device is readonly"
