Subject: [PATCH ghau51/ghau40 v10 01/11] AUDIT_CONTAINER_OP message type basic support
Date:   Mon, 21 Dec 2020 12:12:41 -0500
Message-Id: <20201221171251.2610890-2-rgb@redhat.com>
In-Reply-To: <20201221171251.2610890-1-rgb@redhat.com>
References: <20201221171251.2610890-1-rgb@redhat.com>
Precedence: bulk

This defines the message number for the audit container identifier
registration record should the kernel headers not be up to date, gives
the record number a name for printing and allows the record to be
interpreted since it is in the 1000 range like AUDIT_LOGIN.
