    perf pmu: Abstract alias/event struct · c3245d20
    Ian Rogers authored
    In order to be able to lazily compute aliases/events for a PMU, move
    the struct perf_pmu_alias into pmu.c.
    
    Add perf_pmu__find_event and perf_pmu__for_each_event that take a
    callback that is called for the found event or for each event.
    
    The layout of struct pmu and the event/alias list is unchanged but the
    API is altered so that aliases are no longer directly accessed, allowing
    for later changes.
