workqueue: prepare for more tracepoints
Define workqueue_work event class and use it for workqueue_execute_end trace point. Also, move trace/events/workqueue.h include downwards such that all struct definitions are visible to it. This is to prepare for more tracepoints and doesn't cause any functional change. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Frederic Weisbecker <fweisbec@gmail.com>
