How does adding a rename operation to sysctl sound?

Yes that would definitely help.  Of course for the unregister case
we'd still need either an async removal or a no-op as Patrick
suggested.

I am a little concerned that if we have this issue with sysctl
we also have it with proc and sysfs as well.

Indeed.  /proc should be OK because it's all read-only so we don't
take the RTNL anywhere.  But sysfs may well have the same issue.

I think we should watch out for any more attempts at adding
netdev name-based sysfs nodes and nip them in the bud.

Thanks,
