+static bool virtio_mem_vmcore_pfn_is_ram(struct vmcore_cb *cb,

+{
+	struct virtio_mem *vm = container_of(cb, struct virtio_mem,

+	uint64_t addr = PFN_PHYS(pfn);
+	bool is_ram;
+	int rc;
+
+	if (!virtio_mem_contains_range(vm, addr, addr + PAGE_SIZE))

Some more testing revealed that this has to be

if (!virtio_mem_contains_range(vm, addr, PAGE_SIZE))
