      Enable the SCSI mid-layer which translates block requests to SCSI command
      packets. Needed by AHCI, USB Mass Storage, and NVMe drivers that expose
      disks as SCSI devices.

    depends on RT_USING_BLK
    default y
    help
      Register disk-type SCSI devices (direct-access). Keep enabled unless you
      intentionally drop support for SCSI disks.

    bool "CD-ROM device on SCSI"
    depends on RT_USING_SCSI
    depends on RT_USING_BLK
    default y
    help
      Provide SCSI CD-ROM device emulation (read-only block devices). Disable
      only if optical-style devices are never needed.
