in the same vein:

http://bcache.evilpiepirate.org/

from the main page:

"Bcache is a patch for the Linux kernel to use SSDs to cache other block devices. It's analogous to L2Arc for ZFS,
but Bcache also does writeback caching, and it's filesystem agnostic. It's designed to be switched on with a minimum
of effort, and to work well without configuration on any setup. By default it won't cache sequential IO, just the random
reads and writes that SSDs excel at. It's meant to be suitable for desktops, servers, high end storage arrays, and perhaps
even embedded."

it was submitted to linux kernel mailing list a bunch of time, the last one:
