The code is also not very flexible for extending support for new commands. This patch series address these issues, cleaning up the implementation and making REPORT SUPPORTED OPERATION CODES fully functional. E.g., with these changes, sg_opcodes can be used for listing all SCSI commands that are supported by libata-scsi and a device.
