First of all, glad to see us getting rid of the duplicate lib eventually! :)

Please note that this might result in hopefully just a minor merge issue
with net-next. Looks like patch 4/7 touches test_maps.c and test_verifier.c,
which moved to a new bpf selftest suite [1] this net-next cycle. Seems it's
just log buffer and some renames there, which can be discarded for both
files sitting in selftests.

Thanks,
Daniel
