Yep, I initially considered it, nevertheless given you solved part of the complication I can add it now ;). The only technical reason for not using RCU is if certain users of the notifiers are registering and unregistering at high frequency through objects that may need to be freed quickly. I can tell the KVM usage of the mmu notifiers is sure fine to use RCU. Then I will have to update KVM so that it will free the kvm structure after waiting a quiescent point to avoid kernel crashing memory corruption after applying your changes to the mmu notifier.
