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.
