Subject: [PATCH 1/3] workqueue: Calling destroy_work_on_stack() to pair with INIT_WORK_ONSTACK()
Date: Tue, 07 Jan 2014 16:50:05 +0800 [thread overview]
Message-ID: <1389084605.3650.66.camel@cliu38-desktop-build> (raw)
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().
