Hello, I'm trying to retrieve info in BPF_MAP_UPDATE_ELEM. And I have noticed that the function fetch_bpf_obj_info is used to fetch info but not using the bpf syscall. I want to ask if it is right choice to retrieve the BPF obj info by using syscall bpf BPF_OBJ_GET_INFO_BY_FD? Or should I just use the function fetch_bpf_obj_info?
