Pull audit updates from Paul Moore:
 "A small set of audit patches for v5.11 with four patches in total and
  only one of any real significance.

  Richard's patch to trigger accompanying records causes the kernel to
  emit additional related records when an audit event occurs; helping
  provide some much needed context to events in the audit log. It is
  also worth mentioning that this is a revised patch based on an earlier
  attempt that had to be reverted in the v5.8 time frame.

  Everything passes our test suite, and with no problems reported please
  merge this for v5.11"
