Trying to use bpf BPF_OBJ_GET_INFO_BY_FD to retrieve btf_id in syscall decoder BPF_MAP_UPDATE_ELEM and BPF_MAP_LOOKUP_ELEM. But the syscall BPF_OBJ_GET_INFO_BY_FD is failed and return errno 77, which is "File descriptor in bad state". When I run my demo with the same code, it is fine and able to retrieve btf info. Do you have any views or suggestions on this issue?
