This url is best for others to clone from:

It should be noted that there are more cache replacement policies
available in Joe's thin-dev branch via the "basic" policy, see:
drivers/md/dm-cache-policy-basic.c

(these basic policies include fifo, lru, lfu, and many more)

agk's patches are here:
http://people.redhat.com/agk/patches/linux/editing/series.html

But agk hasn't staged all the required patches yet.  I've imported agk's
editing tree (and a couple other required patches that I previously
posted to dm-devel, which aren't yet in agk's tree) into the
'dm-for-3.8' branch on my github tree here:
git://github.com/snitm/linux.git

This 8 patch patchset from Joe should apply cleanly ontop of my
'dm-for-3.8' branch.

But if all you care about is a tree with all the changes then please
just use Joe's github 'thin-dev' branch.
