    perf: New helper to prevent full dynticks CPUs from stopping tick · 026249ef
    Frederic Weisbecker authored
    Provide a new helper that help full dynticks CPUs to prevent
    from stopping their tick in case there are events in the local
    rotation list.
    
    This way we make sure that perf_event_task_tick() is serviced
    on demand.
