Besides CD-ROMs, three more device types are interesting for SG_IO: media changers, tapes and of course disks.
Starting with this patch, we will whitelist a few more commands for these devices. For media changers, enable "INITIALIZE ELEMENT STATUS" and "REQUEST VOLUME ELEMENT ADDRESS". A few changer-specific commands were already enabled by chance because they overlapped commands that are valid for other classes: "EXCHANGE MEDIUM" and "SEND VOLUME TAG", "INITIALIZE ELEMENT STATUS WITH RANGE".
