All current users (IDE, SCSI and virtio-blk) happen to share this 20 characters limit. Still, it should be left to device models. They already enforce their limits. They have to, as the DriveInfo limit only affects legacy -drive serial=..., not the qdev properties. usb-storage, which doesn't limit serial number length, also uses DriveInfo for -usbdevice. But that doesn't provide access to DriveInfo serial. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
