    perf: Kick full dynticks CPU if events rotation is needed · 12351ef8
    Frederic Weisbecker 提交于
    Kick the current CPU's tick by sending it a self IPI when
    an event is queued on the rotation list and it is the first
    element inserted. This makes sure that perf_event_task_tick()
    works on full dynticks CPUs.
