Don't mean to side-track this thread, but does this mean you've
changed your mind on the previous virtio_net thread [1] ?

Or maybe I'm just misreading your response there? And instead I
could re-spin the virtio_net but dropping the first patch and
dealing with RTNL in the code like this series is doing?

For some reason I was under the impression that the virtio_net
series and others like it (like this igb series) were being held
back until locking work Stanislav is doing is done.
