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.
