Doing this makes the code much more readable. That's borne out by the fact that this patch removes code. "used" also happens to be the number that we need to return back to the slab code when our shrinker gets called. Keeping this value as opposed to free makes the next patch simpler. So, 'struct kvm' is kzalloc()'d. 'struct kvm_arch' is a structure member (and not a pointer) of 'struct kvm'. That means they start out zeroed. I _think_ they get initialized properly by kvm_mmu_change_mmu_pages(). But, that only happens via kvm ioctls. Another benefit of storing 'used' intead of 'free' is that the values are consistent from the moment the structure is allocated: no negative "used" value.
