mainline inclusion from mainline-5.14-rc2 commit 937654ce497fb6e977a8c52baee5f7d9616302d9 category: bugfix bugzilla: 174606 https://gitee.com/openeuler/kernel/issues/I4DDEL
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
--------------------------------
ASan reports some memory leaks when running:
# perf test "42: BPF filter"
The first of these leaks is caused by obj_buf never being deallocated in __test__bpf.
This patch adds the missing free.
