[PATCH 1/3] perf/core: fixing filename for start/stop filters

From: Mathieu Poirier
Date: Fri Jul 15 2016 - 18:26:23 EST


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.
