Merge tag 'xfs-merge-6.18' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Carlos Maiolino:
 "For this merge window, there are really no new features, but there are
  a few things worth to emphasize:

   - Deprecated for years already, the (no)attr2 and (no)ikeep mount
     options have been removed for good

   - Several cleanups (specially from typedefs) and bug fixes

   - Improvements made in the online repair reap calculations

   - online fsck is now enabled by default"
