perf diff: Start moving to support matching more than two hists We want to match more than two hists, so that we can match more than two perf.data files and moreover, match hist_entries (buckets) in multiple events in a group. So the "baseline"/"leader" will instead of a ->pair pointer, use a list_head, that will link to the pairs and hists__match use it. Following that perf_evlist__link will link the hists in its evsel groups.
