Linux kernel recently added support for kernel modules https://lore.kernel.org/bpf/20201110011932.3201430-5-andrii@kernel.org/ In such cases, a type id in the kernel needs to be presented as (btf id for modules, btf type id for this module). Change __builtin_btf_type_id() to return 64bit value so libbpf can do the above encoding. Differential Revision: https://reviews.llvm.org/D91489
