I can (vaguely) imagine devices with stripe sizes >= 2GiB in the not too distant future. Especially clusters with high speed interconnect and RAM-backed devices. There's no harm in an application doing smaller I/O. It should always choose appropriate values itself anyway. But it seems cleaner to report the numbers derived from actual drive topology. -- Jamie -- 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
