Merge branch 'stable-4.10' of git://git.infradead.org/users/pcmoore/audit

Pull audit updates from Paul Moore:
 "After the small number of patches for v4.9, we've got a much bigger
  pile for v4.10.

  The bulk of these patches involve a rework of the audit backlog queue
  to enable us to move the netlink multicasting out of the task/thread
  that generates the audit record and into the kernel thread that emits
  the record (just like we do for the audit unicast to auditd).

  While we were playing with the backlog queue(s) we fixed a number of
  other little problems with the code, and from all the testing so far
  things look to be in much better shape now. Doing this also allowed us
  to re-enable disabling IRQs for some netns operations ("netns: avoid
  disabling irq for netns id").

  The remaining patches fix some small problems that are well documented
  in the commit descriptions, as well as adding session ID filtering
  support"
