Eric, I don't think we can do this.
Fundamentally, any time a user operation changes the configuration of the networking, we must hold the RTNL.
Eliding the RTNL for lookups is fine, but for things that change state it is not.
I therefore think you'll need to rework the arp_ioctl() portions of the commit that introduced this regression.
