From: Sjur Brændeland <sjur.brandeland@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 got smaller so hopefully this a step in the right direction.
This refactoring also make introduction of rproc_serial cleaner.
As requested I also added a patch for not initializing buffers.
I have tested the VIRTIO_CONSOLE device by looping large amount of data through character device and tty, with lockdep and slub-debug on. This looks stable for me. I've also done a simple test of splice.
Thanks, Sjur
