Pull xfs fixes from Darrick Wong:
 "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"
