I'm not sure whether I wanna remove or add WARN_ON_ONCE() on it. That
part has gone through some changes and seen some bugs. Can we please
do the following instead at least for now?

if (!(worker->flags & WORKER_NOT_RUNNING)) {
WARN_ON_ONCE(worker->pool->gcwq->cpu != cpu);
atomic_inc(get_pool_nr_running(worker->pool));
}

Thanks.
