c7d2dc2a20 [SCSI] libosd: osd_sense: OSD_CFO_PERMISSIONS
Add one more important cdb_field_offset that can be returned with
scsi_invalid_field_in_cdb. It is the offset of the permissions_bit_mask
field in the capabilities structure.

Interestingly, the offset is the same for V1/V2

98f3aea2bd [SCSI] libosd: SCSI/OSD Sense decoding support
Implementation of the osd_req_decode_sense() API. Can be called by
library users to decode what failed in command executions.

Add SCSI_OSD_DPRINT_SENSE Kconfig variable. Possible values are:
0 - Do not print any errors to messages file <KERN_ERR>
1 - (Default) Print only decoded errors that are not recoverable.
    Recoverable errors are those that the target has complied with
    the request but with a warning. For example read passed end of
    object will return zeros after the last valid byte.
2- Print all errors.
