This was fixed with this commit:
http://git.kernel.org/cgit/linux/kernel/git/device-mapper/linux-dm.git/commit/?h=for-next&id=47821767d26af4073fcfdfb3b96704f24a23416f

I'll be sending it to Linus at some point this coming week (along with
other DM fixes that are staged in the 'for-next' branch of
linux-dm.git).
