sd needs to detect and handle SBC-3 correctly
driver - device drivers
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.
Current SBC-2 specs also removed these mode pages.
- Blocks deleted (Bug #348: ZFS should handle DKIOCGMEDIAINFOEXT failure)
- Related to Bug #348: ZFS should handle DKIOCGMEDIAINFOEXT failure added
- Related to Bug #7811: dont send obsolete mode pages to SSDs, SATA, SBC2 and later conforming devices added
- Status changed from New to Feedback
With #7811 resolved, we don't send the MODE SENSE for pages 3 and 4. Anything else to do here?
