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/com= mit/?h=3Dfor-next&id=3D6c00531c6affa42b165df73a1eac3289bc45f4c4 https://git.kernel.org/cgit/linux/kernel/git/device-mapper/linux-dm.git/com= mit/?h=3Dfor-next&id=3D51d1a5abcd0e88cb4528f35643245ea59cf234f1 Feel free to pick them up from patchwork or cherry-pick from linux-dm.git Thanks!
