From: Zqiang <qiang.zh...@windriver.com> This patch tracing workqueue name instead of it's address, the new format is as follows.
workqueue_queue_work: work struct=0000000084e3df56 function= drm_fb_helper_dirty_work workqueue=events req_cpu=256 cpu=1 This tell us to know which workqueue our work is queued.
