From 17a2634bcb88e52bd637fdaa47d7ff0bddb0188f Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Mon, 6 Jun 2016 07:36:06 -0700 Subject: [PATCH] perf test: Ignore .scale and other special files 'perf test' tries to parse all entries in /sys/devices/cpu/events/. Ignore the special entries like '.scale', which cannot be directly parsed as an event. This patch assumes all files containing a '.' are special and can be ignored.
