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

Pull quota, reiserfs, udf and ext2 updates from Jan Kara:
 "The branch contains changes to quota code so that it does not modify
  persistent flags in inode->i_flags (it was the only place in kernel
  doing that) and handle it inside filesystem's quotaon/off handlers
  instead.

  The branch also contains two UDF cleanups, a couple of reiserfs fixes
  and one fix for ext2 quota locking"
