Great, thanks for testing!  Did you happen to look at the performance of
your testing?  If so, is it comparable/better/worse?

FYI, I went ahead and added your Tested-by: to this commit:
https://git.kernel.org/cgit/linux/kernel/git/device-mapper/linux-dm.git/commit/?h=for-next&id=e596370123136b37757f4c7d01fb6a6cba26452b

And I also staged the entire series in linux-next (for 3.20 at
earliest).  Still have much more testing to do on these changes but
it'll be good to let them soak in linux-next over the holiday break.

OK, hopefully you'll hear back from the maintainers on that thread soon.
