This is nicely orthogonal to dm-cache.

dm-cache tries to move a working set of fixed size blocks into a cache
to optimise both read and write.  dm-lc focusses solely on optimising
bursty writes and uses a journal based structure to accomodate
variable sized blocks.

The next step is to get some third party users to post their
experiences with it, and get some feedback on the code itself from
Mike Snitzer.

If I get time I'll integrate it with my test suite.
