Currently, each of six different types of failure triggers a single WARN_ON_ONCE(), and it is then necessary to stare at the rcu_torture_stats(), Reader Pipe, and Reader Batch lines looking for inappropriately non-zero values. This can be annoying and error-prone, so this commit provides a separate WARN_ON_ONCE() for each of the six error conditions and adds short comments to each to ease error identification.

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.
