[PATCH 10/18] perf report: Cache cumulative callchains

From: Namhyung Kim It is possble that a callchain has cycles or recursive calls. In that case it'll end up having entries more than 100% overhead in the output. In order to prevent such entries, cache each callchain node and skip if same entry already cumulated. Cc: Arun Sharma Cc: Frederic
