I agree with this - ioctl() on actual block devices is more direct, and the quirks needed to get the right sysfs dir awkward. It would be good to use the same ioctl() as other OSes if there are any exporting the same information. However, sysfs, being text based, is easier to extend with new values that can be used without recompiling programs, e.g. from scripts, so it's useful to have the same information there. To link them, an ioctl() which returns an unambiguous reference to the appropriate sysfs entry would be good too. E.g. perhaps returning a file descriptor of the appropriate directory. -- 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
