Code like:
WARN_ON(foo())
looks like an assertion and might not be expected to have any side
effects.
When testing if a function with side-effects fails a construct like
if (foo())
WARN_ON(1);
makes the intent more obvious.
nfsd has several WARN_ON calls where the test has side effects, so it
would be good to change them. These cases don't really need the
WARN_ON. They have never failed in 8 years of usage so let's just
remove the WARN_ON wrapper.

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.
