Not sure where that would end up in a perfect world. But isn't SATA related to SAS? And isn't SAS using SCSI commands? And if ATAPI is essentially SCSI commands, and everything other then disks use ATAPI on ATA, then that makes ATA disks the odd ball, and mangling it into line with everything else isn't that bad (since all other ATA devices are close to SCSI already). -- Len Sorensen - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
