As Jiri noted, we tested v2 I think, so if there is a v4 build we could 
give a spin, just let us know.

In the meantime, for kpatch, we figured that we could just temporarily 
disable CONFIG_DEBUG_INFO_BTF in the scripts/link-vmlinux.sh file during 
kpatch builds ... that would leave kernel code intact, but skip the BTF 
generation step (for which kpatch doesn't need anyway).

Thanks,
