Pull audit updates from Paul Moore:
 "In the finest of holiday of traditions, I have a number of gifts to
  share today. While most of them are re-gifts from others, unlike the
  typical re-gift, these are things you will want in and around your
  tree; I promise.

  This pull request is perhaps a bit larger than our typical PR, but
  most of it comes from Jan's rework of audit's fanotify code; a very
  welcome improvement. We ran this through our normal regression tests,
  as well as some newly created stress tests and everything looks good.

  Richard added a few patches, mostly cleaning up a few things and and
  shortening some of the audit records that we send to userspace; a
  change the userspace folks are quite happy about.

  Finally YueHaibing and I kick in a few patches to simplify things a
  bit and make the code less prone to errors.

  Lastly, I want to say thanks one more time to everyone who has
  contributed patches, testing, and code reviews for the audit subsystem
  over the past year. The project is what it is due to your help and
  contributions - thank you"
