Message-ID: <20070513215226.GB3198@tv-sign.ru> Date: Mon, 14 May 2007 01:52:26 +0400 From: Oleg Nesterov <oleg@...sign.ru> To: Andrew Morton <akpm@...ux-foundation.org>, "Rafael J. Wysocki" <rjw@...k.pl> Cc: LKML <linux-kernel@...r.kernel.org>, Michal Piotrowski <michal.k.k.piotrowski@...il.com>, Alex Dubov <oakad@...oo.com>, Pierre Ossman <drzeus@...eus.cx> Subject: [PATCH] for 2.6.22, make freezeable workqueues singlethread 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.
