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" * tag 'xfs-5.1-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: clean up xfs_dir2_leaf_addname xfs: zero initialize highstale and lowstale in xfs_dir2_leaf_addname xfs: clean up xfs_dir2_leafn_add xfs: Zero initialize highstale and lowstale in xfs_dir2_leafn_add
