note that both revs of my BSG patch for STGT are actually not using iovecs because we are dealing with contigious userspace memory from STGT obtained via scsi_get_[out,in]_buffer() and not userspace scatterlist memory so there is not a hard requirement for them.
I am not sure if I read this correct, but just to be on the safe side,
some future changes in the memory management may require scatterlist
support, so best if we don't assume contiguous user-space memory would
be used for ever in the command flow on stgt.
