Cathy?If you use alloc_ordered_workqueue directly instead ofThe only thing that flag does is exempting the workqueue from possible
create_singlethread_workqueue you can pass a format string and don't
need the separate allocation.
But I'm not sure if Tejun is fine with using __WQ_LEGACY directly..
flush deadlock check as we don't know whether WQ_MEM_RECLAIM on a
legacy workqueue is intentional. There's no reason to add it when
converting to alloc_ordered_workqueue(). Just decide whether it needs
forward progress guarantee and use WQ_MEM_RECLAIM if so.
