Well, it fixes a problem on one of my test systems where max_ws_blocks, by virtue of being 64 bits, clobbers opt_xfer_blocks causing rw_len and thus max_sectors to be set incorrectly. We haven't run into that issue on real hardware. Probably because scsi_debug is the only driver reporting $LUDICROUS_NUMBER as the max hw transfer.

I agree that the value chosen by scsi_debug in this case is very low and we should fix that. -- Martin K.
