Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4

Pull ext4 updates from Ted Ts'o:
 "Clean ups and miscellaneous bug fixes, in particular for the new
  collapse_range and zero_range fallocate functions.  In addition,
  improve the scalability of adding and remove inodes from the orphan
  list"
