Oops, I can read. :) Doing a build now...

I found:
https://docs.kernel.org/bpf/bpf_devel_QA.html
But it doesn't seem to cover a bunch of stuff (no way to prebuild the
tests, no info on building the test modules).
This seems to be needed:
make O=regression-bug -C tools/testing/selftests/bpf/test_kmods
But then the booted kernel doesn't load it (missing signatures?)
Anyway, I'll keep digging...
