btrfs_page_mkwrite() is a struct vm_operations_struct callback and we define that structure in file.c. Currently the function is in inode.c and has to be exported to be used in file.c, which makes no sense because it's not used anywhere else. So move btrfs_page_mkwrite() from inode.c and into file.c. While at it do a few minor style changes: 1) Capitalize the first word of every comment and end each sentence with punctuation; 2) Avoid splitting some statements into two lines when everything fits in 85 characters or less.

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.
