Hello Chris,

I read through this and at the moment one questions come in my mind:

http://btrfs.wiki.kernel.org/images-btrfs/7/72/Chunks-overview.png

Looking at this picture, when I'm going to implement the dedup code, do I also
have to take care to spread the blocks over the different devices or is
there already infrastructure in place that automates that process?

I'm looking forward to this and will use it as an implementation road
map.
