stable inclusion from stable-5.10.54 commit 2ae8f40a8fdfc013ab9fb5440b2e570c1e4f1708 bugzilla: 175586 https://gitee.com/openeuler/kernel/issues/I4DVDU Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=2ae8f40a8fdfc013ab9fb5440b2e570c1e4f1708 -------------------------------- [ Upstream commit faf3ac30 ] ASan reports several memory leaks while running: # perf test "82: Use vfs_getname probe to get syscall args filenames" Two of these are caused by some refcounts not being decreased on perf-script exit, namely script.threads and script.cpus. This patch adds the missing __put calls in a new perf_script__exit function, which is called at the end of cmd_script. This patch concludes the fixes of all remaining memory leaks in perf test "82: Use vfs_getname probe to get syscall args filenames".
