However, it even extends chains that have already been submitted to hardware. This is dangerous because there is no way of knowing whether the hardware has already read the DMA memory in question or not. Fix this by splitting the chain list into two. One for submitted requests and one for requests that have not yet been submitted. Only extend the latter.
