Commit 5a2798ab32ba ("bpf: Add BTF_ID_LIST/BTF_ID/BTF_ID_UNUSED macros") added support to calculate btf_ids during linux build time. Patch #2 replaced runtime mechanism with new build-time btf_id computation mechanism. Patch #1 also fixed a minor issue to use "static" instead of "extern" for variable declaration to conform to actual variable scope.
