- * Ver 0.2   Jan 26 97   Fixed bug in cleanup_module() and added emulation

- *                        to Janos Farkas for pointing this out.
- *                       Avoid using bitfields in structures for m68k.
- *                       Added Scatter/Gather and DMA support.
- * Ver 0.4   Dec  7 97   Add support for ATAPI PD/CD drives.
- *                       Use variable timeout for each command.
- * Ver 0.5   Jan  2 98   Fix previous PD/CD support.
- *                       Allow disabling of SCSI-6 to SCSI-10 transformation.
- * Ver 0.6   Jan 27 98   Allow disabling of SCSI command translation layer
- *                        for access through /dev/sg.
- *                       Fix MODE_SENSE_6/MODE_SELECT_6/INQUIRY translation.
- * Ver 0.7   Dec 04 98   Ignore commands where lun != 0 to avoid multiple
- *                        detection of devices with CONFIG_SCSI_MULTI_LUN
- * Ver 0.8   Feb 05 99   Optical media need translation too. Reverse 0.7.
- * Ver 0.9   Jul 04 99   Fix a bug in SG_SET_TRANSFORM.
- * Ver 0.91  Jun 10 02   Fix "off by one" error in transforms
