Sure thing. So I've never done this sort of thing, so forgive me for
being new at it. Would it make sense to merge this change to sysctl-next
as-is today and put a frozen branch sysclt-next-bpf to reflect this,
which bpf-next can merge. And then sysctl-next just continues to chug on
its own? As-is my goal is to keep sysctl-next as immutable as well.

Or is there a better approach you can recommend?
