Pull selinux update from Paul Moore:
 "We've got an unusually small SELinux pull request for v5.15 that
  consists of only one (?!) patch that is really pretty minor when you
  look at it.

  Unsurprisingly it passes all of our tests and merges cleanly on top of
  your tree right now, please merge this for v5.15"
