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

Pull quota interface unification and misc cleanups from Jan Kara:
 "The first part of the series unifying XFS and VFS quota interfaces.

  This part unifies turning quotas on and off so quota-tools and
  xfs_quota can be used to manage any filesystem.  This is useful so
  that userspace doesn't have to distinguish which filesystem it is
  working with.  As a result we can then easily reuse tests for project
  quotas in XFS for ext4.

  This also contains minor cleanups and fixes for udf, isofs, and ext3"
