Pull 9p fixes from Eric Van Hensbergen:
"Misc set of fixes for 9p.
Most of these clean up warnings we've gotten out of compilation tools,
but several of them were from inspection while hunting down a couple
of regressions.
The most important one is 75b396821c ("fs/9p: remove unnecessary and
overrestrictive check") which caused a regression for some folks by
restricting mmap in any case where writeback caches weren't enabled.
Most of the other bugs caught via inspection were type mismatches"

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.
