函数原型：static u64 collect_timerqueue(struct timerqueue_head *head, struct list_head *firing, u64 now)

返回类型：u64

参数：

类型参数名称
struct timerqueue_head *head
struct list_head *firing
u64now
767  i等于0
769  当next等于返回计时器的最早的过期时间循环
773  ctmr等于container_of - cast a member of a structure out to the containing structure*@ptr: the pointer to the member.*@type: the type of the container struct this is embedded in.*@member: the name of the member within the struct.(next, structcpu_timer, node)
774  expires等于cpu_timer_getexpires(ctmr)
776  如果i先自加恒等于MAX_COLLECTED或now小于expires则返回:expires
779  firing等于1
780  cpu_timer_dequeue(ctmr)
781  添加链表项
