Message-ID: <1389084605.3650.66.camel@cliu38-desktop-build> Date: Tue, 07 Jan 2014 16:50:05 +0800 From: Chuansheng Liu <chuansheng.liu@...el.com> To: tj@...nel.org Cc: linux-kernel@...r.kernel.org, chuansheng.liu@...el.com Subject: [PATCH 1/3] workqueue: Calling destroy_work_on_stack() to pair with INIT_WORK_ONSTACK() In case CONFIG_DEBUG_OBJECTS_WORK is defined, it is needed to call destroy_work_on_stack() which frees the debug object to pair with INIT_WORK_ONSTACK().
