From 245bad8eb45fca36638da53fb0a361397a707001 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Tue, 1 Sep 2015 15:52:46 -0700 Subject: [PATCH] perf stat: Quieten failed to read counter message Since 3b3eb0445 running perf stat on a system without backend-stalled-cycles spits out ugly warnings by default. Since that is quite common, make the message a debug message only. We know anyways that the counter wasn't read by the normal output.
