Hey Josef,

Nice job with this target, you need to contribute to DM more ;)

I've staged your target for the 4.1 merge in linux-dm.git's 'for-next'
branch (with a few small fixes for nits/typos).

FYI, I'll likely rebase 'for-next' once more for 4.1 given a conflicting
4.0 change to DM core still needs to land upstream (you can see the
merge conflict in 'for-next' at the moment).  But that won't impact your
target at all (other than changing the 4.1 commit id).

Thanks,
Mike
