A dying worker is first moved from pool->workers to pool->dying_workers in set_worker_dying() and removed from pool->dying_workers in detach_dying_workers(). The whole procedure is in the some lock context of wq_pool_attach_mutex. So pool->dying_workers is useless, just remove it and keep the dying worker in pool->workers after set_worker_dying() and remove it in detach_dying_workers() with wq_pool_attach_mutex held.
