RCU maybe a little trickier here Eric. Actions could be shared i.e. 
example, it is possible to have a policer action restricting rates for a
group of flows  across multiple netdevices etc. Since action stats get
written to by different CPUs concurrently. It could be probably done if
one was to implement per-cpu stats which get summed-up when user space
