What has happened with this patch set?

No idea. cc'ing Chris directly. Chris, if the patchset looks good,
can you please route them through the btrfs tree?

lol looking at the patchset again, I'm not sure that's obviously the
right tree. It can either be cgroup, block or btrfs. If no one
objects, I'll just route them through cgroup.

We'll have to coordinate a bit during the next merge window but I don't have a problem with these going in through cgroup. Dave does this sound good to you?

I'd like to include my patch to do all crcs inline (instead of handing off to helper threads) when io controls are in place. By the merge window we should have some good data on how much it's all helping.
