Slab poisoning gave me a General Protection Fault on the
	atomic_dec(&__task_cred(p)->user->processes);
line of release_task() called from wait_task_zombie(),
every time my dd to USB testing generated a memcg OOM.

Just curious, was it with the wait-on-pagereclaim patch?

Yes, that's what I was trying to test.

I have noticed the other email already. Sorry for the noise.
