Message-Id: <1348481238-6138-2-git-send-email-laijs@cn.fujitsu.com> Date: Mon, 24 Sep 2012 18:07:03 +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 01/10] workqueue: always pass flush responsibility to next depriving the responsibility make the code complex, we pass it to the next unconditionally. After this change, we don't need to go back to repeat cascading, so we use "break" to exit the loop. The loop will be remove in later patch.
