 - Revert the ALLOC_USERDATA cleanup because it caused subtle
   behavior regressions.

 "There are a couple of bug fixes and some small code cleanups that came
  in recently:

   - Minor code cleanups

   - Fix a superblock logging error

   - Ensure that collapse range converts the data fork to extents format
     when necessary

   - Revert the ALLOC_USERDATA cleanup because it caused subtle behavior
     regressions"

* tag 'xfs-5.4-merge-8' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
  xfs: avoid unused to_mp() function warning
  xfs: log proper length of superblock
  xfs: revert 1baa2800e6 ("xfs: remove the unused XFS_ALLOC_USERDATA flag")
  xfs: removed unneeded variable
  xfs: convert inode to extent format after extent merge due to shift
