Subject[PATCH RFC v2 12/12] integrity: store reference to mok keyring
Date
Store a reference to the mok keyring in system keyring code. The
reference is only set when trust_moklist is true. This prevents the mok
keyring from linking to either the builtin or secondary trusted keyrings
with an empty mok list.
