Hi Greg,

Below are few build errors in libbpf code:

Here are few libbpf commits:
> David Vernet <void@...ifault.com>
>      libbpf: Don't take direct pointers into BTF data from st_ops
> 
> Eduard Zingerman <eddyz87@...il.com>
>      libbpf: Sync progs autoload with maps autocreate for struct_ops maps
> 
> Kui-Feng Lee <thinker.li@...il.com>
>      libbpf: Convert st_ops->data to shadow type.
> 
> Kui-Feng Lee <thinker.li@...il.com>
>      libbpf: Find correct module BTFs for struct_ops maps and progs.
> 
> Andrii Nakryiko <andrii@...nel.org>
>      libbpf: use stable map placeholder FDs
