Hi,

it would be great if Debian kernels could also enable the
CONFIG_DEBUG_INFO_BTF option, quoting from
http://www.brendangregg.com/blog/2020-11-04/bpf-co-re-btf-libbpf.html:

| CONFIG_DEBUG_INFO_BTF=y
|
| These new BPF binaries are only possible if this kernel config
| option is set. It adds about 1.5 Mbytes to the kernel image (this is
| tiny in comparison to DWARF debuginfo, which can be hundreds of
| Mbytes). Ubuntu 20.10 has already made this config option the
| default, and all other distros should follow. Note to distro
| maintainers: it requires pahole >= 1.16.

regards
