From f114d6eff76d20b521d8716e969e71b1f56f82b5 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Tue, 8 Sep 2015 10:58:53 +0300 Subject: [PATCH] perf evlist: Fix splice_list_tail() not setting evlist Commit d49e46950772 ("perf evsel: Add a backpointer to the evlist a evsel is in") updated perf_evlist__add() but not perf_evlist__splice_list_tail(). This illustrates that it is better if perf_evlist__splice_list_tail() calls perf_evlist__add() instead of duplicating the logic, so do that. This will also simplify a subsequent fix for propagating maps.
