[PATCH ghau51/ghau40 v9 01/11] AUDIT_CONTAINER_OP message type basic support

From: Richard Guy Briggs
Date: Sat Jun 27 2020 - 11:19:18 EST


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.
