当计时器过期时，将调用回调函数my _ timer_callback。

When the timer expires, the callback function (my_timer_callback) is invoked.

时间轮是一个buckets集合，其中每个bucker 表示将来计时器过期的一个时间块。

The timer wheel is a collection of buckets in which each bucket represents a chunk of time in the future for timer expiration.

youdao

从用户角度看，timer_list包含一个过期时间，一个回调函数（当/如果计时器过期），以及一个用户提供的上下文。

From a user's perspective, timer_list contains an expiration time, a callback function (when/if the timer expires), and a user-provided context.

原始计时器实现只是按照过期顺序将计时器实现双重链接。

The original timer implementation simply kept timers doubly linked in expiration order.

youdao

拥有一个经过初始化的计时器之后，用户现在需要设置过期时间，这通过调用mod _ timer来完成。

With an initialized timer, the user now needs to set the expiration time, which is done through a call to mod_timer.

youdao

使用jiffies作为时间粒度，定义了几个组，它们表示将来的过期时段(其中每个组通过一列计时器表示)。

Using jiffies as the granularity of time, a number of groups is defined that represents future periods of expiration (where each group is represented by a list of timers).

所以你需要使用一个计时器或一个单独的进程来处理密钥的过期。

So you need to use a timer or a separate process to handle expiration of keys.
