    perf pmu: Scan type early to fail an invalid PMU quickly · 88ed9184
    Ian Rogers authored
    Scan sysfs PMU's type early so that format and aliases aren't
    attempted to be loaded if the PMU name is invalid.
    
    This is the case for event_pmu tokens in parse-events.y where a wildcard
    name is first assumed to be a PMU name.
