Luis Chamberlain 8ccee8c19c shmem: set shmem_writepage() variables early
shmem_writepage() sets up variables typically used *after* a possible huge
page split.  However even if that does happen the address space mapping
should not change, and the inode does not change either.  So it should be
safe to set that from the very beginning.

This commit makes no functional changes.

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.
