Using Rusty's suggestion I've respun the patch removing the special copy function. I've tested this patch in a guest kernel with and without qemu supplying serial numbers for the block devices and it's working as expected. When qemu supplies serial numbers, the correct value is supplied to /sys/block/vdX/serial and can be used by udev for generating disk/by-id paths (without
