From: Riccardo Mancini <rickyman7@gmail.com> stable inclusion from stable-5.10.54 commit c9c101da3e83563e595693282167c04592b5536d bugzilla: 175586 https://gitee.com/openeuler/kernel/issues/I4DVDU Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit fc56f54f6fcd5337634f4545af6459613129b432 ] ASan reports a memory leak when running: # perf test "49: Synthesize attr update" Caused by evlist not being deleted. This patch adds the missing evlist__delete and removes the perf_cpu_map__put since it's already being deleted by evlist__delete.
