queue_delayed_work和schedule_delayed_work的区别

参考链接：https://zhuanlan.zhihu.com/p/558543523

queue_delayed_work 跟schedule_delayed_work 类似，

区别：

• schedule_delayed_work 是在系统默认的工作队列上执行一个work，
• queue_delayed_work需要自行指定工作队列。类似地，schedule_delayed_work也是依赖于queue_delayed_work实现的。

static inline bool schedule_delayed_work(struct delayed_work *dwork,
                     unsigned long delay)
{
    return queue_delayed_work(system_wq, dwork, delay);
}
