Yep, routing all the BPF selftest patches via bpf/bpf-next tree is the only
viable model that works for us in BPF case, in fact also looks like BPF
selftests are the busiest subdir in #commits so avoiding merge conflicts is
crucial. Whenever appropriate, most fixes or new features are very often
accompanied in a patch set with extensive selftests for BPF, so it has a
deep dependency on the two trees.
