I see that struct > btf_enum64 is introduced only in kernel 6.0, not yet packaged.
It does look like libbpf has now added a hard dependency on v6.0+ kernel even though they said it will have "transparent handling of older kernels". I have mentioned it in https://github.com/libbpf/libbpf/issues/562#issuecomment-1237299951. So, we either need to wait for some fix from libbpf upstream or wait for the Debian kernel team to update to v6.0 after its released next month. -- Regards Sudip
