Hi Andrii, When opening a modules BTF file (e.g. /sys/kernel/btf/i40e), can I somehow get the kernels BTF object ID value (via that FD)? I think I want the BTF object IDs as displayed by 'btftool btf'. That code walks all IDs via bpf_btf_get_next_id() and then gets the FD via bpf_btf_get_fd_by_id(). I'm looking for a more direct way than having to walk all IDs... (p.s. Cc. Larysa, I also looked at your code, which like bpftool end-up walking all BTF IDs and extends libbpf with internal btf_obj_id to keep track). --Jesper
