I'm auditing dm-devel's patchwork and would just like to confirm that
others would still like to see this go in?

Patch in question is captured here:
https://patchwork.kernel.org/patch/29088/

Mike C.,
An earlier version of this patch got your "Looks ok.":
https://patchwork.kernel.org/patch/23946/
Can I translate that to your "Acked-by:" if/when I rebase and repost?

Please advise,
Mike
