Specifically, does something like makes sense?

struct scatterlist my_sg; /* somewhere, but iser_send_command  stack */

if(!sc->use_sg) {
  	my_sg.page   = virt_to_page(sc->request_buffer);
	my_sg.length = sc->request_bufflen;
	my_sg.offset = 0;
}

now continue as ususal to process my_sg (it can't be on the stack

Or.
