Andrii Nakryiko 68b08647c7 libbpf: Detect minimal BTF support and skip BTF loading, if missing ... Detect whether a kernel supports any BTF at all, and if not, don't even attempt loading BTF to avoid unnecessary log messages like: libbpf: Error loading BTF: Invalid argument(22) libbpf: Error loading .BTF into kernel: -22. BTF is optional, ignoring.
