Subject: [PATCH 06/18] security/keys: export key_lookup()
For in-kernel consumers one cannot readily assign a user (eg when
running from a workqueue), so the normal key search permissions
cannot be applied.
This patch exports the 'key_lookup()' function for a simple lookup
of keys without checking for permissions.
