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?
