Subject: [PATCH 0/4] put_user_page: new put_user_page_dirty*() helpers

From: John Hubbard <jhubbard@...dia.com>

Hi,

Here is the first small batch of call site conversions for put_page()
to put_user_page().

This batch includes some, but not all of the places that benefit from the
two new put_user_page_dirty*() helper functions. (The ordering of call site
conversion patch submission makes it better to wait until later, to convert
the rest.)

There are about 50+ patches in my tree [1], and I'll be sending out the
remaining ones in a few more groups:

    * The block/bio related changes (Jerome mostly wrote those, but I've
      had to move stuff around extensively, and add a little code)

    * mm/ changes

    * other subsystem patches

    * an RFC that shows the current state of the tracking patch set. That
      can only be applied after all call sites are converted, but it's
      good to get an early look at it.

This is part a tree-wide conversion, as described in commit fc1d8e7cca2d
("mm: introduce put_user_page*(), placeholder versions").
