Pull misc filesystem updates from Jan Kara:
 "A couple of small bugfixes and cleanups for quota, udf, ext2, and
  reiserfs"

* tag 'fs_for_v5.2-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
  quota: check time limit when back out space/inode change
  fs/quota: erase unused but set variable warning
  quota: fix wrong indentation
  udf: fix an uninitialized read bug and remove dead code
  fs/reiserfs/journal.c: Make remove_journal_hash static
  quota: remove trailing whitespaces
  quota: code cleanup for __dquot_alloc_space()
  ext2: Adjust the comment of function ext2_alloc_branch
  udf: Explain handling of load_nls() failure
