From: Andrii Nakryiko <andrii@kernel.org> mainline inclusion from mainline-5.16-rc1 commit 53df63ccdc0258118e53089197d0428c5330cc9c category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I5EUVD CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... ------------------------------------------------- Update struct_ops selftests to always specify "struct_ops" section prefix. Libbpf will require a proper BPF program type set in the next patch, so this prevents tests breaking.
