Merge tag 'xfs-5.10-merge-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Darrick Wong:
"The biggest changes are two new features for the ondisk metadata: one
to record the sizes of the inode btrees in the AG to increase
redundancy checks and to improve mount times; and a second new feature
to support timestamps until the year 2486.
We also fixed a problem where reflinking into a file that requires
synchronous writes wouldn't actually flush the updates to disk; clean
up a fair amount of cruft; and started fixing some bugs in the
realtime volume code.
Summary:
- Clean up the buffer ioend calling path so that the retry strategy
isn't quite so scattered everywhere.
- Clean up m_sb_bp handling.
- New feature: storing inode btree counts in the AGI to speed up
certain mount time per-AG block reservation operatoins and add a
little more metadata redundancy.
- New feature: Widen inode timestamps and quota grace expiration
timestamps to support dates through the year 2486.
- Get rid of more of our custom buffer allocation API wrappers.
- Use a proper VLA for shortform xattr structure namevals.
- Force the log after reflinking or deduping into a file that is
opened with O_SYNC or O_DSYNC.
- Fix some math errors in the realtime allocator"
