| |
-stable review patch. If anyone has any objections, please let us know. ---------------------
From: Oleg Nesterov <oleg@tv-sign.ru>
It is a known fact that freezeable multithreaded workqueues doesn't like CPU_DEAD. We keep them only for the incoming CPU-hotplug rework.
Sadly, we can't just kill create_freezeable_workqueue() right now, make them singlethread.
