Now that all workqueues are non-reentrant, flush[_delayed]_work_sync() are equivalent to flush[_delayed]_work(). Drop the separate implementation and make them thin wrappers around flush[_delayed]_work(). * start_flush_work() no longer takes @wait_executing as the only left user - flush_work() - always sets it to %true. * __cancel_work_timer() uses flush_work() instead of wait_on_work().
