Interesting, thank you.
You're talking about https://github.com/mingzhao/dm-cache
right?
I've seen it but couldn't figure out how to use it...
Nice to have it merged though even if it is not immediately useful...

IMHO bcache will never be a viable option due to maintenance overhead of
custom patched kernel and (more important) because bcache require special
preparation/formatting of block devices and therefore can't be plugged to
existing file systems with data.
I see that flashcache matured since 2011 and these days it doesn't cripple
performance-wise as it used to.
EnhancIO is just fantastic and (hopefully) immediately useful. Package is
ready and only lacking reasonable testing so you're very welcome to try it. :)
