From 936f1f30bb7892f010670f1edebc419d47b139b1 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Tue, 16 Jan 2018 15:14:52 +0200 Subject: [PATCH] perf tools: Get rid of unused 'swapped' parameter from perf_event__synthesize_sample() There is never a need to synthesize a 'swapped' sample, so all callers to perf_event__synthesize_sample() pass 'false' as the value to 'swapped'. So get rid of the unused 'swapped' parameter.
