I also added this for the casual reader to get up to speed more quickly,
please check that it makes sense.

    Committer note:
    
    When we use -c or a period=N term in the event definition, then we don't
    need to ask the kernel, via perf_event_attr.sample_type |=
    PERF_SAMPLE_PERIOD, to put the event period in each sample, as we know
    it already, it is in perf_event_attr.sample_period.
