Subject: [PATCH 09/16] perf hists: Cleanup filtering functions
Date: Thu, 21 Jan 2016 13:00:42 -0300	[thread overview]
Message-ID: <1453392049-5825-10-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1453392049-5825-1-git-send-email-acme@kernel.org>

From: Namhyung Kim <namhyung@kernel.org>

The hists__filter_by_xxx functions share same logic with different
filters.  Factor out the common code into the hists__filter_by_type.
