Use filemap_fdatawrite_range instead of opencoding the logic using filemap_fdatawrite_wbc. There is a slight change in the conversion as nr_to_write is now set to LONG_MAX instead of double the number of the pages in the range. LONG_MAX is the usual nr_to_write for WB_SYNC_ALL writeback, and the value expected by lower layers here.

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 reStructuredText 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.
