1088  timer等于hrtimer
1089  pmu等于pmu
1093  如果task_ctx_nr恒等于perf_sw_context则返回
1100  interval等于hrtimer_interval_ms
1101  如果interval小于1则interval等于hrtimer_interval_ms等于set default to be dependent on timer tick just* like original code
1104  hrtimer_interval等于ns_to_ktime(NSEC_PER_MSEC * interval)
1106  raw_spin_lock_init( & hrtimer_lock)
1107  hrtimer_init - initialize a timer to the given clock*@timer: the timer to be initialized*@clock_id: the clock to be used*@mode: The modes which are relevant for intitialization:* HRTIMER_MODE_ABS, HRTIMER_MODE_REL, HRTIMER_MODE_ABS_SOFT,*
