From: Sjur Br?ndeland <sjur.brandeland at stericsson.com> I thought rebasing rproc_serial to linux-next was going to be trivial. But when starting the merge I realized that I had to refactor the the patches from Masami Hiramatsu. The splice support has the same issue as I faced, with different type of buffers in the out_vq. So I ended up refactoring the splice functionality. The code size
