Hi, this is a follow up for [1] which has been nacked mostly because Tetsuo was able to find a simple workload which can trigger a race where no-eligible task is reported without a good reason. I believe the patch2 addresses that issue and we do not have to play dirty games with throttling just because of the race. I still believe that patch proposed in [1] is a useful one but this can be addressed later.
This series comprises 2 patch. The first one is something I meant to do loooong time ago, I just never have time to do that. We need it here to handle CLONE_VM without CLONE_SIGHAND cases. The second patch closes the race.
I didn't get to test this throughly so it is posted as an RFC.
Feedback is appreciated of course.
