From 4059ffd09d694f704e18a4baf97fc0016c32e9ad Mon Sep 17 00:00:00 2001 From: Mathieu Poirier Date: Mon, 18 Jul 2016 10:43:05 -0600 Subject: [PATCH] perf/core: Fix file name handling for start/stop filters Binary file names have to be supplied for both range and start/stop filters but the current code only processes the filename if an address range filter is specified. This code adds processing of the filename for start/stop filters.
