Re: [PATCH bpf-next v7 0/7] libbpf: Implement BTFGen

Hello:

This series was applied to bpf/bpf-next.git (master)

CO-RE requires to have BTF information describing the kernel types in
order to perform the relocations. This is usually provided by the kernel
itself when it's configured with CONFIG_DEBUG_INFO_BTF. However, this
configuration is not enabled in all the distributions and it's not
available on kernels before 5.12.

It's possible to use CO-RE in kernels without CONFIG_DEBUG_INFO_BTF
support by providing the BTF information from an external source.
BTFHub[0] contains BTF files to each released kernel not supporting BTF,
for the most popular distributions.
