函数名称：Recomputes cpu_base::*next_timer and returns the earliest expires_next but* does not set cpu_base::*expires_next, that is done by hrtimer_reprogram

函数原型：static ktime_t __hrtimer_get_next_event(struct hrtimer_cpu_base *cpu_base, unsigned int active_mask)

返回类型：ktime_t

参数：

类型参数名称
struct hrtimer_cpu_base *cpu_base
unsigned intactive_mask
570  struct hrtimer * next_timer = NULL
571  expires_next等于KTIME_MAX
573  如果非softirq_activated且active_mask按位与HRTIMER_ACTIVE_SOFT则
574  active等于active_bases按位与HRTIMER_ACTIVE_SOFT
575  softirq_next_timer = NULL
576  expires_next等于__hrtimer_next_event_base(cpu_base, NULL, active, KTIME_MAX)
579  next_timer等于softirq_next_timer
582  如果active_mask按位与HRTIMER_ACTIVE_HARD则
583  active等于active_bases按位与HRTIMER_ACTIVE_HARD
584  next_timer等于next_timer
585  expires_next等于__hrtimer_next_event_base(cpu_base, NULL, active, expires_next)
589  返回:expires_next
