H A D | evlist.c | bfd1b83d Mon Sep 14 22:18:11 CDT 2020 Namhyung Kim <namhyung@kernel.org> perf evlist: Fix cpu/thread map leak
Asan reported leak of cpu and thread maps as they have one more refcount than released. I found that after setting evlist maps it should release it's refcount.
It seems to be broken from the beginning so I chose the original commit as the culprit. But not sure how it's applied to stable trees since there are many changes in the code after that.
