Paolo, List Please find a patch that adds emulation of SG_IO to the synchronous function bdrv_ioctl()/iscsi_ioctl(). Previously we have only supported emulation for this ioctl in iSCSI for the asynchronous function iscsi_aio_ioctl() since that is the only place scsi-generic uses SG_IO.
By adding support for SG_IO to iscsi_ioctl() this makes scsi-block and scsi-disk work too. Since scsi-block/scsi-disk never worked with iscsi, and only scsi-generic worked, this is not a new regression. So whether this should go in now or wait until post 1.2 is for your disgression. regards ronnie sahlberg
