After reviewing some code, I found that it's wrong to grab config_lock, because other context will grab such lock and flush_workqueue(), and there is no gurantee that recv_work() will grab the lock first. Will it be acceptable to export blk_queue_enter()? I can't think of other way to retrieve the`nsock` reference at the entry of recv_work().Then I think it is easier to pass `nsock` from `recv_thread_args`, which can be thought as local variable too.
