commit 6e73e92b155c868ff7fce9d108839668caf1d9be upstream.
When running an nfs stress test, I see quite a few cached replies that
don't match up with the actual request. The first comment in
replay_matches_cache() makes sense, but the code doesn't seem to
match... fix it.
This isn't exactly a bugfix, as the server isn't required to catch every
case of a false retry. So, we may as well do this, but if this is
fixing a problem then that suggests there's a client bug.

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.
