With an upcoming change we would like to invoke bpftool checks from the run-qemu action (https://github.com/libbpf/ci/pull/37). This action requires two environment variables, KERNEL and REPO_ROOT, set in order to function. Make sure to set them now. Long term we should probably make them explicit input arguments instead of implicit global state, but there are many more such instances that we need to clean up.
