383  当非break_test()循环
384  mplete: - signals a single thread waiting on this completion*@x: holds the state of this particular completion* This will wake up a single thread waiting on this completion. Threads will be* awakened in the same order in which they were queued.
386  ring_buffer_consumer()
388  set_current_state(睡眠态)
389  如果break_test()则退出
391  进程调度
393  set_current_state() includes a barrier so that the write of current->state* is correctly serialised wrt the caller's subsequent test of whether to* actually sleep:* for (;;) {* set_current_state(TASK_UNINTERRUPTIBLE);* if (!need_sleep)* break;* (就绪态)
395  如果非kthread_should_stop - should this kthread return now?* When someone calls kthread_stop() on your kthread, it will be woken* and this will return true. You should then return, and your return* value will be passed through to kthread_stop().则wait_to_die()
