Merge branch 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs

Pull quota updates from Jan Kara:
 "Quota improvements and some minor cleanups.

  The main portion in the pull request are changes which move i_dquot
  array from struct inode into fs-private part of an inode which saves
  memory for filesystems which don't use VFS quotas"

  udf: One function call less in udf_fill_super() after error detection
