hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICU4YT -------------------------------- LTS commit 06819489ee4c ("selftests/bpf: fix perf_event link info name_len assertion") was backported with stable depend patches: - commit 3ab8f9fc286c ("selftests/bpf: Add cookies check for perf_event fill_link_info test") - commit d9bb36d54939 ("selftests/bpf: Use bpf_link__destroy in fill_link_info tests") However, we do not need these two depend patches and they will cause compiling error of bpf selftests. So let's revert these patches and re-adapt the target commit.
