Yeah, it makes sense to pick this patch into perf/urgent branch since
it's a fixing patch.

Actually, this patch has been merged into the tmp.perf/core branch [1],
after you move it to the perf/urgent branch, I can confirm all other
patches for perf tool in this series have been merged into the
tmp.perf/core branch.

Thanks,
Leo
