I'm unclear to what specifically you're referring -- the
ioctl() used to retrieve the serial number in the guest?
Well, there's not specific ioctl to get a serial number for scsi, but
given that we now have SG_IO passthrough in virtio-blk it should be easy
enough to provide inquiry data and the device identification VPD page
by that way. Not sure how it's handled for ide, maybe that way
is even easier.
Yea, I'm hardly in enamored with the IDE/ATA
diatribe. But in this case displacing the new
ioctl with HDIO_GET_IDENTITY seemed the most
straightforward means to provide access within
an existing interface. Updated patch follows.
