Description

sd currently issues MODE SENSE for page codes 3 and 4 which have been dropped from SBC-3 (the T10 standard for direct-attached block devices), resulting in illegal requests. There are also cases where we may erroneously assume a block device is SBC-3 compliant if it reports SPC-4 compliance.
