But the disks are probed in the same manner as last time (if the disks/controllers are not moved, crashed etc..). So we will end up getting same names.
Oh, but if next_index is 0 in the module (or reset by the init_module code), then also with index = next_index++ things will be the same after rmmod/insmod.
