Re: [RFC PATCH v1 06/37] KVM: guest_memfd: Update kvm_gmem_populate() to use gmem attributes

#ifdef CONFIG_HAVE_KVM_ARCH_GMEM_POPULATE +static bool kvm_gmem_range_is_private(struct gmem_inode *gi, pgoff_t index,

• 		      size_t nr_pages, struct kvm *kvm, gfn_t gfn)
  

+{

• pgoff_t end = index + nr_pages - 1;
• void *entry;
• if (vm_memory_attributes)

• return kvm_range_has_vm_memory_attributes(kvm, gfn, gfn + nr_pages,
  

• 				       KVM_MEMORY_ATTRIBUTE_PRIVATE,
  

• 				       KVM_MEMORY_ATTRIBUTE_PRIVATE);
  

Can't compile kvm_range_has_vm_memory_attributes() if CONFIG_KVM_VM_MEMORY_ATTRIBUTES is not set.
