Hi Greg,
Below are few build errors in libbpf code:
Here are few libbpf commits:
David Vernet void@manifault.com libbpf: Don't take direct pointers into BTF data from st_ops
Eduard Zingerman eddyz87@gmail.com libbpf: Sync progs autoload with maps autocreate for struct_ops maps
Kui-Feng Lee thinker.li@gmail.com libbpf: Convert st_ops->data to shadow type.
Kui-Feng Lee thinker.li@gmail.com libbpf: Find correct module BTFs for struct_ops maps and progs.
Andrii Nakryiko andrii@kernel.org libbpf: use stable map placeholder FDs
