I think the intent is OK...but the real problem that I see is that it 
generates a record also when calling mq_getattr(). Seems like the function 
could be put here

1095         if (u_mqstat != NULL) {
1096                 if (copy_from_user(&mqstat, u_mqstat, sizeof(struct 
mq_attr)))
1097                         return -EFAULT;
1098                 if (mqstat.mq_flags & (~O_NONBLOCK))
1099                         return -EINVAL;

-->                    audret = audit_mq_getsetattr(mqdes, &mqstat);
			if (audret)
				return audret;           
1100         }

omqstat does not need to be recorded does it? AFAICT, this is the status 
buffer going back to the user.
