This patch replaces the nfs_version_mutex and nfs_version_lock with a single RW lock that protects access to the nfs_versions list. The mutex around request_module() seemed unnecessary to me, and I couldn't find any other callers using a lock around calls to request_module() when I looked. At the same time, I saw fs/filesystems.c using a RW lock to protect their filesystems list. This seems like a better idea than a spinlock to me, so I'm also making that change while I'm here.

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.
