From 9afcf930b1fa1158b0878afeba3eff299300dc65 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Mon, 10 Dec 2012 17:29:54 +0900 Subject: perf hists: Exchange order of comparing items when collapsing hists When comparing entries for collapsing put the given entry first, and then the iterated entry. This is not the case of hist_entry__cmp() when called if given sort keys don't require collapsing. So change the order for the sake of consistency. It will be required for matching and/or linking multiple hist entries.
