I know. And I did study the ZIO DMA code (among other things), before I
implemented the IIO DMA code. As you might remember from our last discussion,
my preference is to add the features that are in ZIO but not in IIO to IIO and
then ditch ZIO instead of having two frameworks for the class of devices.
