Subject: [PATCH 04/41] perf stat: Factor out generic metric printing
Date: Tue, 12 Sep 2017 12:09:52 -0300	[thread overview]
Message-ID: <20170912151029.6612-5-acme@kernel.org> (raw)
In-Reply-To: <20170912151029.6612-1-acme@kernel.org>

From: Andi Kleen <ak@linux.intel.com>

The 'perf stat' shadow metric printing already supports generic metrics.
Factor out the code doing that into a separate function that can be
re-used in a later patch.

No behavior changes.

v2: Fix indentation
