Merge tag 'xfs-5.1-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux 

Pull xfs cleanups from Darrick Wong:
 "Here's a few more cleanups that trickled in for the merge window.

  It's all fixes for static checker complaints and slowly unwinding
  typedef usage. The four patches here have gone through a few days
  worth of fstest runs with no new problems observed.

  Summary:

   - Fix some clang/smatch/sparse warnings about uninitialized
     variables.

   - Clean up some typedef usage"
