From: Arnaldo Carvalho de Melo <a...@redhat.com> 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.
