The patches are just in the master branch. Hi Mike, I had a look at your DM changes. That sucked (but things looked good). So much so that I want to thank you for tackling this task (and taking one for the team). I'll get this kernel built and tested (using the various DM testsuites: lvm2, cryptsetup, device-mapper-test-suite for dm-thinp and dm-cache).
