perf evlist: Propagate thread maps through the evlist (578e91ec) · Commits · 戴 / test

Propagate evlist's thread_map object through all the evsel objects. It'll be handy to access evsel's threads directly in following patches. The reason is there's no link from evsel to evlist which hold threads map now and evlist is not always available. Signed-off-by:
