And perhaps you are right. At least we can probably kill task->tgid.
And I agree, it would be nice to kill task->pid.

But: I also agree with Peter, we should try to not make the current
code more expensive.

Anyway. Imho, you should not mix the different things in one series.
If you want to fix audit, do not add the patches like 10/12 or 11/12
into this series.

Or 3/12. OK, I agree sys_getppid() in audit_log_task_info() looks
strange at least. Just fix it using the helpers we already have and
add the new helpers later. Or send the patch(es) which adds the new
helpers first.

Or task_pid_nr_init_ns()... For what? We already have task_pid_nr().
Use the helper we already have, or introduce the new one first and
change the current users of task_pid_nr().

In short. Fortunately you do not need to convince me, I do not
maintain audit or namespaces ;) But imho this series looks a bit
