I'd be interested to hear how it performs ...
It'd be a lot more interesting if it were a write-through cache rather
than a write-back cache, wouldn't it?
That's what bcache tries to accomplish, both read and write cache.
It also appears to aim to be more widely usable, rather than the
relatively specific requirements the facebook variant is designed for.

They seem to try and combine both the dedicated ZIL and L2ARC
