[Xen-devel] [PATCH 10/11] xend/pvscsi: recognize also SCSI CDROM devices

[Olaf Hering <olaf@xxxxxxxxx>]

Attaching a CDROM device with 'xm scsi-attach domU /dev/sr0 0:0:0:0'
fails because for some reason the sr driver was not handled at all in
the match list. With the change the above command succeeds and the
device is attached.
