The reason for this is one we will add more device filesystems. Second
most likely we will see merger of shared code. Where will we place that?

Sorry about the confusion. By saying devfs2 I mean a full device
filesystem. We should call it something else. Any ideas?

YEs we will need a /dev/gfx/0/frame1 but you will have to use read and
write instead of mmap. This is what Linus wants as pointed out in the
discussion between me, him and Viro.
