Sigh. We're at -rc7 and I don't think it's worth working around that for a cleanup series. So I'm inclined to just defer this series until the next -rc cycle. If BPF merges reasonably early in the next merge window then please promptly send this along and I should be able to squeak it into 6.15-rc1.
