Subject: [PATCH 0/3] Fix crash with fscrypt + Landlock
Date: Mon, 13 Mar 2023 15:12:28 -0700	[thread overview]
Message-ID: <20230313221231.272498-1-ebiggers@kernel.org> (raw)

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()
