Subject: [PATCH 05/11] perf test: Ignore .scale and other special files
Date: Mon,  6 Jun 2016 18:04:37 -0300	[thread overview]
Message-ID: <1465247083-4763-6-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1465247083-4763-1-git-send-email-acme@kernel.org>

From: Andi Kleen <ak@linux.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.
