Frankly I'd love it if my changes could make it into v4.9 through the XFS
tree.  They've passed xfstests both with and without DAX, and they've passed
all the targeted testing I've been able to throw at them.  If that works, we
can integrate Jan's changes on top of them during the v4.9 cycle and merge for
v4.10.

I'll work on incorporating changes for your feedback, Dave, and hopefully have
a v4 out by the end of the day.
