Ah, whoops. "Block cache" - it uses one block device to cache another, 
it's intended for SSDs. It's summarized decently in the documentation 
patch, which if I'd thought harder would've been the first email...

Second patch also has relevant commentary:
http://thread.gmane.org/gmane.linux.kernel/979978
http://thread.gmane.org/gmane.linux.kernel/979979

Currently all the necessary functionality for read only is close to 
done, I'm now doing stress testing. I'm hoping to have it Stable For Me 
and read/write done in a week or two, at which point it should be ready 
for people to start playing with.
