Rusty Russell 39214915f5 KVM: kvm_vm_ioctl_get_dirty_log restore "nothing dirty" optimization ... kvm_vm_ioctl_get_dirty_log scans bitmap to see it it's all zero, but doesn't use that information. Avi says: Looks like it was used to guard kvm_mmu_slot_remove_write_access(); optimizing the case where the guest just leaves the screen alone (which it usually does, especially in benchmarks). I'd rather reinstate that optimization. See 90cb0529dd where the damage was done. It's pretty simple: if the bitmap is all zero, we don't need to do anything to clean it.
