Does this mean that dm-writeboost is similar to btier ? If so, this 
makes me wonder which of these two subsystems would be the best 
candidate for upstream inclusion. As far as I know btier doesn't split 
bio's. The source code of btier can be downloaded from 
http://sourceforge.net/projects/tier/.
