nfs_update_folio has code to extend a write to the entire page under
certain conditions. With the support for large folios this now
suddenly extents to the variable sized and potentially much larger folio.
Add code to limit the extension to the page boundaries of the start and
end of the write, which matches the historic expecation and the code
comments.

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.
