It is not worth doing this kind of complex thing, usually, only a few pages on the invalid list. The *really* heavily case is kvm_mmu_zap_all() which can be speeded up by using generation number, this is a todo work in kvm wiki: http://www.linux-kvm.org/page/TODO: O(1) mmu invalidation using a generation number I am doing this work for some weeks and will post the patch out during these days. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
