I don't know the Linux SCSI stack, so some basic questions for you :).

With scsi-generic I can send SCSI commands to a device.  How is bsg
different?  The bsg code looks cleaner than sg but they both boil down
to issuing SCSI requests using the Linux block layer AFAICT.

Can you explain what advantages this patch series brings over scsi-generic?

Thanks,
Stefan
