[ Upstream commit cf3075fb36c6a98ea890f4a50b4419ff2fff9a2f ] In function __extent_writepage() we always pass page start to @delalloc_start for writepage_delalloc(). Thus we don't really need @delalloc_start parameter as we can extract it from @page. Remove @delalloc_start parameter and make __extent_writepage() to declare @page_start and @page_end as const.

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.
