This patch set exposed a few functions in libbpf. All these newly added API functions are helpful for JIT based bpf compilation where .BTF and .BTF.ext are available as in-memory data blobs.
Patch #1 exposed several btf_ext__* API functions which are used to handle .BTF.ext ELF sections. Patch #2 refactored the function bpf_map_find_btf_info() and exposed API function btf__get_map_kv_tids() to retrieve the map key/value type id's generated by bpf program through BPF_ANNOTATE_KV_PAIR macro.
