Subject: [PATCH RFC v2 09/12] KEYS: add a reference to mok keyring
Date: Mon, 26 Jul 2021 13:13:16 -0400	[thread overview]
Message-ID: <20210726171319.3133879-10-eric.snowberg@oracle.com> (raw)
In-Reply-To: <20210726171319.3133879-1-eric.snowberg@oracle.com>

Expose the .mok keyring created in integrity code by adding
a reference.  This makes the mok keyring accessible for keyring
restrictions in the future.
