From c51fd6395d67a6d414834db7f892c95594247d6f Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Tue, 24 May 2016 12:52:39 -0700 Subject: [PATCH] perf stat: Add missing aggregation headers for --metric-only CSV When in CSV mode --metric-only outputs an header, unlike the other modes. Previously it did not properly print headers for the aggregation columns, so the headers were actually shifted against the real values. Fix this here by outputting the correct headers for CSV. v2: Indent array.
