类型参数名称
struct kthread_work *work
953  struct kthread_flush_work fwork = {KTHREAD_WORK_INIT(work, kthread_flush_work_fn), COMPLETION_INITIALIZER_ONSTACK(done), }
958  bool noop = false

968  如果非链表为空则sert @work before @pos in @worker
970  否则如果current_work恒等于work则sert @work before @pos in @worker
973  否则noop = true
