From 72a128aa083a7f4cc4f800718aaae05d9c698e26 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Tue, 23 Sep 2014 10:01:41 +0900 Subject: perf tools: Move callchain config from record_opts to callchain_param So that all callchain config parameters can be read/written to a single place. It's a preparation to consolidate handling of all callchain options.
