From: Riccardo Mancini <rickyman7@gmail.com> stable inclusion from stable-5.10.54 commit b768db7f8070617405ab02fffe1b7a0633fcac63 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 233f2dc1c284337286f9a64c0152236779a42f6c ] ASan reports a memory leak related to session->evlist while running: # perf test "41: Session topology". When perf_data is in write mode, session->evlist is owned by the caller, which should also take care of deleting it. This patch adds the missing evlist__delete().
