Subject: Re: [PATCH v5 07/12] KEYS: Introduce link restriction to include builtin, secondary and machine keys

Hi Eric,
The subject line above is too long. According to
Documentation/process/submitting-patches.rst the "the ``summary`` must
be no more than 70-75 characters".

Sorry for the patch churn. With the keyring name change to ".machine",
the restriction name should also reflect this change.
