I did consider it, but the end result doesn't even build, so I unpulled again..

I get some libbpf error, and I'm just not interested in trying to
debug it. This has clearly not been tested well enough to be merged.

libbpf: failed to find '.BTF' ELF section in /home/torvalds/v2.6/linux/vmlinux
Error: failed to load BTF from /home/torvalds/v2.6/linux/vmlinux: No
data available
Failure to generate vmlinux.h needed for the recommended BPF skeleton support.
To disable this use the build option NO_BPF_SKEL=1.
Alternatively point at a pre-generated vmlinux.h with VMLINUX_H=<path>.

the build system assumptions are clearly completely broken.
