Libata is a self admitted kludge. /dev/sdx => scsi disk Libata has stuck itself under the scsi disk driver, so you are right that not all scsi disks have a ata_host kludge, only the imposers should have one. One path I have never chased is for an external usb connected drive. Scsi commands are sent a across the usb bus so there is probably not any libata involvement.
