Fixed, and tweaked the headers (already did that last time around so
nothing new, you just didn't pick up my headers for your v2). I pushed
your patchset to linux-next (for 3.21), see:
https://git.kernel.org/cgit/linux/kernel/git/device-mapper/linux-dm.git/log/?h=for-next
Ondrej and Milan, please let us know if you hit any problems with this
patchset and/or branch.
