We need to use READ CAPACITY 16 to determine features like 4k physical sector size, and support for UNMAP. This pair of patches let us try it on really recent SCSI drives and all LibATA drives (where it's emulated by libata so we know they support it). It will not be tried on USB devices, as the USB layer overrides their claims of support for recent SCSI versions. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
