Pull quota and udf updates from Jan Kara:
 "The pull contains quota changes which complete unification of XFS and
  VFS quota interfaces (so tools can use either interface to manipulate
  any filesystem).  There's also a patch to support project quotas in
  VFS quota subsystem from Li Xi.

  Finally there's a bunch of UDF fixes and cleanups and tiny cleanup in
  reiserfs & ext3"
