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

Browse Source 
Pull ext4 updates from Ted Ts'o:
 "Add new ioctls to set and get the file system UUID in the ext4
  superblock and improved the performance of the online resizing of file
  systems with bigalloc enabled.

  Fixed a lot of bugs, in particular for the inline data feature,
  potential races when creating and deleting inodes with shared extended
  attribute blocks, and the handling of directory blocks which are
  corrupted"
