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:

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.
