At first, thank you for tackling this. It was really a problem using callchain on non trivial perf session. But there's another effort to address this problem in other direction. You might want to see below link [1]. Patch 1/8 does the thing and it seems Arnaldo already merged it into his tree.
Arnaldo, is there any issue prevents others from being merged?
