We're moving sysctls out of kernel/sysctl.c as its a mess. We

kernel/sysctl.c has grown to an insane mess and its easy to run
into conflicts with it. The effort to move them out is part of this.

Given the desire is to route this via sysctl-next and we're not shortly
before but after the merge win, could we get a feature branch for bpf-next
to pull from to avoid conflicts with ongoing development cycle?

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?

Are you able to merge the pr/bpf-sysctl branch into your sysctl-next tree?

https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git/log/?h=pr/bpf-sysctl

This is based off common base for both trees (3123109284176b1532874591f7c81f3837bbdc17)
so should only pull in the single commit then.

Yup. That worked just fine. I pushed it.

Great, thanks!
