Thanks for the report, I've staged a fix here:
https://git.kernel.org/cgit/linux/kernel/git/device-mapper/linux-dm.git/commit/?h=dm-4.5&id=512167788a6fe9481a33a3cce5f80b684631a1bb

Waiting for the 4.5 merge window sense this isn't a serious problem
(it'll make its way back to stable@ kernels once merged)
