Specifically, issue an IBPB flush on BPF JIT memory reuse. Skip\nenabling the IBPB flush if the BPF dispatcher is already using a retpoline\nsequence.\n\nThis hardening applies only when BPF-JIT is in use. Guard the enabling\nunder CONFIG_BPF_JIT so that bugs.c still builds with CONFIG_BPF_JIT=n.",
