From b278c364b35ae940b05f6a9edf8061fc886cd09e Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Tue, 8 Sep 2015 10:58:54 +0300 Subject: [PATCH] perf evlist: Fix missing thread_map__put in propagate_maps() perf_evlist__propagate_maps() incorrectly assumes evsel->threads is NULL before reassigning it, but it won't be NULL when perf_evlist__set_maps() is used to set different (or NULL) maps. Thus thread_map__put must be used, which works even if evsel->threads is NULL.
