[PATCH v5 04/15] perf pmu-events: Add separate metric from pmu_event

Ian Rogers
2023-01-26T23:38:03Z

Create a new pmu_metric for the metric related variables from
pmu_event but that is initially just a clone of pmu_event. Add
iterators for pmu_metric and use in places that metrics are desired
rather than events. Make the event iterator skip metric only events,
and the metric iterator skip event only events.
