Message-Id: <1345040741-5508-7-git-send-email-js1304@gmail.com> Date: Wed, 15 Aug 2012 23:25:41 +0900 From: Joonsoo Kim <js1304@...il.com> To: Tejun Heo <tj@...nel.org> Cc: linux-kernel@...r.kernel.org, Joonsoo Kim <js1304@...il.com> Subject: [PATCH v3 6/6] workqueue: use system_highpri_wq for unbind_work To speed cpu down processing up, use system_highpri_wq. As scheduling priority of workers on it is higher than system_wq and it is not contended by other normal works on this cpu, work on it is processed faster than system_wq.
