As discussed at LSF the SCSI stack already knows about several error conditions, it's just not well documented. Also there are some more conditions upper layers might be interested in. This patchset improves the documentation of the existing I/O error codes and adds three more error codes, ENOSPC for thin provisioning failure, ENODATA for medium error, and ENXIO for an invalid or removed device. Changes since the initial version: - Correctly document all return codes in __scsi_error_from_host_byte() - Set hostbyte status in scsi_check_sense() - Return ENXIO on invalid or removed device Hannes Reinecke (5): scsi: Document enhanced error codes scsi: Set hostbyte status in scsi_check_sense() scsi: return ENOSPC on thin provisioning failure scsi: Return ENODATA on medium error scsi: Return ENXIO on invalid device block/blk-core.c | 9 +++++++++ drivers/scsi/scsi_error.c | 28 +++++++++++++--------------- drivers/scsi/scsi_lib.c | 29 ++++++++++++++++++++++++++++- include/scsi/scsi.h | 3 ++- 4 files changed, 52 insertions(+), 17 deletions(-) -- 1.7.12.4 -- 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
