This series fixes a bug, found by syzbot, where when a filesystem was
being unmounted, the fscrypt keyring was destroyed before inodes have
been released by the Landlock LSM.

Eric Biggers (3):
  fscrypt: destroy keyring after security_sb_delete()
  fscrypt: improve fscrypt_destroy_keyring() documentation
  fscrypt: check for NULL keyring in fscrypt_put_master_key_activeref()
