[arch-general] aufs2 patch to work for archlinux kernel

I fixed aufs2 to work in archlinux kernel. I had to remove some patches to aufs2-standalone.patch you guys made so it would work. This will mean we have to drop unionfs for this to work. http://arch-live.isawsome.net/devel/aufs2-standalone.patch patch for aufs2 to work with kernel 2.6.29 http://arch-live.isawsome.net/devel/aufs2-linux-2.6.29.patch Unionfs need do_splice_to and do_splice_from to be vfsub_splice_to and vfsub_splice_from. Problem was that those functions are in fs/aufs/vfsub.c file. Anyways I fixed the error since we are not using unionfs anymore if aufs2 is added in. I hope this helps.
