内核机制1—workqueue

1. 会创建线程的worqueue

wq = alloc_ordered_workqueue("%s", WQ_MEM_RECLAIM | WQ_HIGHPRI, "f_fstb"); //prio=100 cfs 0-7
# ps -AT | grep f_fstb
root           645   645     2       0      0 rescuer_thread      0 I f_fstb

wq = create_singlethread_workqueue("s_async"); //prio=100 cfs 0-7
# ps -AT | grep s_async
root           300   300     2       0      0 rescuer_thread      0 I s_async
