Dan, you are merging DAX patches these days. So probably you should add
yourself to 'FILESYSTEM DIRECT ACCESS (DAX)' in MAINTAINERs. Or I can start
picking patches for fsdax to my tree if you are too busy but I think your
tree is easier as there are less chances for conflicts etc.

In either case this patch looks OK to me so feel free to add
