From: Namhyung Kim Date: Thu, 8 Jan 2015 00:45:47 +0000 (+0900) Subject: perf diff: Fix output ordering to honor next column X-Git-Tag: v4.1~178^2~117^2~9 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=56495a8affabe35aa0d94aae050d3e0e60d0455f;p=platform%2Fkernel%2Flinux-amlogic.git perf diff: Fix output ordering to honor next column When perf diff prints output, it sorts the entries using baseline field by default, but entries which don't have baseline are not sorted properly. This patch makes it sorted by values of next column.
