Subject: [PATCH V2 1/3] perf/core: Fixing filename for start/stop filters
Date: Mon, 18 Jul 2016 10:43:05 -0600
Message-ID: <1468860187-318-2-git-send-email-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <1468860187-318-1-git-send-email-mathieu.poirier@linaro.org>

Binary file names have to be supplied for both range and start/stop
filters but the current code only process the filename if an
address range filter is specified.  This code adds processing of
the filename for start/stop filters.
