Hi Stephen,
Please add git://git.infradead.org/users/willy/linux-dax.git xarray to linux-next. It is based on -rc1. You will find some conflicts against Dan's current patches to DAX; these are all resolved correctly in the xarray-20180615 branch which is based on next-20180615. In a masterstroke of timing, I'm going to be on a plane to Tokyo on Monday. If this causes any problems, please just ignore the request for now and we'll resolve it when I'm available to fix problems.
