If the ".BTF" elf section exists, libbpf will try to create a btf_fd (through BPF_BTF_LOAD). If that fails, it will still continue loading the bpf prog/map without the BTF. If the bpf_object has a BTF loaded, it will create a map with the btf_fd. libbpf will try to figure out the btf_key_id and btf_value_id of a map by finding the BTF type with name "<map_name>_key" and "<map_name>_value". If they cannot be found, it will continue without using the BTF.
