Agreed, Vladimir's work is more complete than mine, my work was just a
RFC to show the concept, it was far from being ready or testable with
some use cases such as bonding/bridge/ovs/etc...

Let me take a look at the current series, and if I see that the
rcu/dev_hold approach is more lightweight then i will suggest it to
Vladimir and he can make the final decision.
