Subject: [PATCH 05/11] perf test: Ignore .scale and other special files
From: Andi Kleen <ak@...ux.intel.com>
'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.
