25  dev等于Operations for contexts that are safe from preemption/interrupts. These* operations verify that preemption is disabled.(evtdev)
27  如果此条件成立可能性小(为编译器优化)(expires == KTIME_MAX)则
31  lockevents_switch_state - set the operating state of a clock event device*@dev: device to modify*@state: new state* Must be called with interrupts disabled !
32  next_event等于KTIME_MAX
33  返回:0
36  如果此条件成立可能性小(为编译器优化)(clockevent_state_oneshot_stopped(dev))则

hrtimer_reprogramWhen a timer is enqueued and expires earlier than the already enqueued* timers, we have to check, whether it expires earlier than the timer for* which the clock event device was armed.* Called with interrupts disabled and base->cpu_base.lock held
