From b24c28f794e1821c1bba3ef7e9e948ab77ee00ac Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Thu, 4 Oct 2012 21:49:41 +0900 Subject: [PATCH] perf hists: Introduce struct he_stat The struct he_stat is for separating out statistics data of a hist entry. It is required for later changes. It's just a mechanical change and should have no functional differences.
