Both backstores and fabrics use arrays of struct scatterlist to describe data buffers. However TCM used struct se_mems, basically a linked list of scatterlist entries. We are able to simplify the code by eliminating this intermediate data structure and just using struct scatterlist[] throughout. Also, moved attachment of task to cmd out of transport_generic_get_task and into allocate_control_task and allocate_data_tasks. The reasoning is that it's nonintuitive that get_task should automatically add it to the cmd's task list -- it should just return an allocated, initialized task. That's all it should do, based on the function's name, so either the function shouldn't do it, or the name should change to encapsulate the entire essence of what it does.
