Move page unlocking during page writeback out of mpage_submit_page() into the callers. This will allow writeback in data=journal mode to keep the page locked for a bit longer. Since page unlocking it tightly connected to increment of mpd->first_page (as that determines cleanup of locked but unwritten pages), move page unlocking as well as mpd->first_page handling into a helper function.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
