I think it's totally different story.
Here I have block size smaller than page size and it's not new to the filesystem -- similar to 1k block size with 4k page size. So I was able to re-use most of infrastructure to handle the situation.
Block size bigger than page size is backward task. I don't think I know enough to understand how hard it would be. I guess not easy. :)
