Merge tag 'fs.vfsuid.ima.v6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/idmapping

Pull vfsuid cleanup from Christian Brauner:
 "This moves the ima specific vfs{g,u}id_t comparison helpers out of the
  header and into the one file in ima where they are used.

  We shouldn't incentivize people to use them by placing them into the
  header. As discussed and suggested by Linus in [1] let's just define
  them locally in the one file in ima where they are used"
