From: Damien Le Moal <damien.lemoal@xxxxxxxxxxxxxxxxxx> The REPORT_SUPPORTED_OPERATION_CODES command allows checking for support of commands that have the same opcode but different service actions, such as READ 32 and WRITE 32. However, the current implementation of scsi_report_opcode() only allows checking an operation code without a service action differentiation. Add the "sa" argument to scsi_report_opcode() to allow passing a service action. If a non-zero service action is specified, the reporting options field value is set to 3 to have the service action field taken into account by the device. If no service action field is specified (zero), the reporting options field is set to 1 as before.
