Doh, I just keep breaking stuff. There are unfortunately known issues with running on top of dm/md - they are high on my list but I've had a lot on my plate lately =/ Worst part of the md/dm issues are that passthrough mode is affected. Apologies for having to find out the hard way. Thanks for the heads up about the cgroup issue. I'm gonna post a new version on lkml just as soon as I have time to finish the md/dm stuff and thoroughly test it myself.
