Date: Wed, 20 Mar 2013 03:28:01 +0800 From: Lai Jiangshan <laijs@...fujitsu.com> To: Tejun Heo <tj@...nel.org>, linux-kernel@...r.kernel.org Cc: Lai Jiangshan <laijs@...fujitsu.com> Subject: [PATCH 01/21] workqueue: add missing POOL_FREEZING When we create a new pool via get_unbound_pool() when freezing. the pool->flags' POOL_FREEZING is incorrect. Fix it by adding POOL_FREEZING if workqueue_freezing. (wq_mutex is already held for accessing workqueue_freezing.)
