Re: [PATCH v1 8/8] virtio-mem: kdump mode to sanitize /proc/vmcore access


+static bool virtio_mem_vmcore_pfn_is_ram(struct vmcore_cb *cb,
+                                        unsigned long pfn)
+       struct virtio_mem *vm = container_of(cb, struct virtio_mem,
+                                            vmcore_cb);
+       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))
