Yes, your suggestion is much cleaner.  This was some of the lingering
doubt I had about where to add it.  While reviewing, I found a duplicate
when called from audit_log_pid_context().  I also found a couple of
functions that don't have sufficient logging coverage
(audit_log_feature_change and audit_log_set_loginuid).

Thanks for the helpful review!
