The code that allowed you to use a blockdev directly proved to have a severe flaw in it and has since bitrotted, since it never went upstream. I'm looking at doing fscache v2.0 and storing all of the data in one file, which would be storable on a blockdev, but it's in the planning stages at the moment.
