From 9b8087d72086b249ff744cee237ad12cc5e9255d Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Thu, 22 Dec 2016 15:03:48 +0900 Subject: [PATCH] perf sched timehist: Enlarge default 'comm_width' Current default value is 20 but it's easily changed to a bigger value as task has a long name and different tid and pid. And it makes the output not aligned. So change it to have a large value as summary shows.
