I want to experiment with mbcache kernel module, but I'm having trouble finding the documentation for it.

If I understood correctly, mbcache allows the use of a fast SSD disk to act as a transparent cache for much slower hard disks.

Where can I find the documentation?

I'm on Linux 3.0.0-17-generic #30-Ubuntu SMP x86_64

There doesn't seem to be any documentation other than the source code itself. I wrote to Andreas Gruenbacher and referenced this question but have not received a reply.

I took a peek at the source code, but the comment isn't really helpful. The userland tools are not mentioned at all (but that is no surprise). Hopefully the mbcache project will share documentation shortly. – jippie Apr 19 '12 at 7:52
I found an alternative called 'flashcache' github.com/facebook/flashcache (if you add that to your answer, I'll accept it for your initial effort) – jippie Aug 13 '12 at 20:23
