Thinking more about this, I think its probably fine to keep the two versions of the irte seperate like in this patch-set. It allows to update the non-posted irte when the posted irte is active at the moment and makes the transition between both irte variants easier. But what I still don't like is the type casting necessary when calling modify_irte(). Can you abstract this and put the decission whether irte or irte_pi is set active into modify_irte? It required to change the interface of modify_irte, but that should be easy.
