And I agree (mostly) with that we should rely on do_notify_parent(). Howver the patch still doesn't look right. First of all, ->autoreap should be per-process, not per-thread. And there are ptrace/mt issues, it seems. Just for example, we should avoid EXIT_TRACE if autoreap in wait_task_zombie() even if we are going to re-notify parent. Yes... and other problems with ptrace. So let me nack this patch for the moment ;) But let me repeat that personally I agree with this change "in general". EXCEPT: do we really want SIGCHLD from the exiting child? I think we do not. I won't really argue though, but this should be discussed and documented. IIUC, with your patch it is still sent. Josh, please give me some time to think and re-check, I'll write another email next week. I am not sure this is really needed, but it seems to me that we need the preparation patch to make this change clear/simple.
