revert "cancel_delayed_work: use del_timer() instead of del_timer_sync()"
As pointed out by Jarek Poplawski, the patch
[WORKQUEUE]: cancel_delayed_work: use del_timer() instead of del_timer_sync()
commit: 071b638689464c6b39407025eedd810d5b5e6f5d
was wrong, it was merged by mistake after that.
From the changelog:
after this patch:
...
delayed_work_timer_fn->__queue_work() in progress.
The latter doesn't differ from the caller's POV,
it does make a difference if the caller calls flush_workqueue() after
cancel_delayed_work(), in that case flush_workqueue() can miss this
work_struct.
