Hi Jens,

As I shared with you before, here are the 2 patches I staged in
linux-next via linux-dm.git's 'for-next' (same as in the patchwork
references above) -- these were staged just so we had linux-next
coverage until you picked them up.

Please pick these up for 4.8 -- the changes are straightforward, are
required for DM's DAX support, and Dan Williams has also acked them:

https://git.kernel.org/cgit/linux/kernel/git/device-mapper/linux-dm.git/commit/?h=for-next&id=6c00531c6affa42b165df73a1eac3289bc45f4c4
https://git.kernel.org/cgit/linux/kernel/git/device-mapper/linux-dm.git/commit/?h=for-next&id=51d1a5abcd0e88cb4528f35643245ea59cf234f1

Feel free to pick them up from patchwork or cherry-pick from
linux-dm.git

Thanks!
Mike
