Hi,

Dave Chinner's head didn't seem to explode...much, when he saw Ira's
series, so I optimistically started taking it from there...this builds on
top of Ira's patchset that he just sent out:

  "[RFC PATCH v2 00/19] RDMA/FS DAX truncate proposal V1,000,002   ;-)" [1]

...which in turn is based on the latest -mmotm.

If Ira's series and this one are both acceptable, then

    a) I'll rework the 41-patch "put_user_pages(): miscellaneous call
       sites" series, and

    b) note that this will take rather longer and will be quite a bit more
       intrusive for each call site (but it's worth it), due to the
       need to plumb the owning struct file* all the way down to the gup()
       call. whew.
