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"
