From 33db4568e1f41efe6d0e4695483f968fc1135bf3 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Fri, 7 Feb 2014 12:06:07 +0900 Subject: perf top: Add --percentage option The --percentage option is for controlling overhead percentage displayed. It can only receive either of "relative" or "absolute". Move the parser callback function into a common location since it's used by multiple commands now. For more information, please see previous commit same thing done to "perf report".
