Yes.  I was waiting until I actually have an implementation, but anyway 
here it is, attached.  The changes are small:

- additional failure kinds mapping more or less to Linux driver_statuses

- defined the format of the LUN.  Unlike vSCSI, there's no support for 
generic hierarchical LUNs.  A single LUN format is specified, that 
supports 256 targets and 16384 LUNs per target.

- clarified multiqueue semantics

I'm planning to update your LLD code to support these changes, but I'll 
gladly accept that someone else does it. :)
