BSG is certainly a ULD, Upper-Layer-Driver that can issue block commands
through block layer and block-queue.

SMP is a block device class that has it's own LLDs.

The way I understand

|---------|      |--------------|      |-----------|
| ULD     |----->|  block layer |----->| block LLD |
|---------|      |--------------|      |-----------|

So I meant block ULD or block layer user code. That is what I meant
by ULD, what do you mean?
