The current virtio block's naming algorithm just supports 18278 (26^3 + 26^2 + 26) disks. If there are more virtio blocks, there will be disks with the same name. Based on commit 3e1a7ff8, add a function "virtblk_name_format()" for virtio block to support mass of disks naming. Notes: - Our naming scheme is ugly. We are stuck with it for virtio but don't use it for any new driver: new drivers should name their devices PREFIX%d where the sequence number can be allocated by ida - sd_format_disk_name has exactly the same logic. Moving it to a central place was deferred over worries that this will make people keep using the legacy naming in new drivers. We kept code idential in case someone wants to deduplicate later.
