A later commit will reduce the size of the RCU watching counter to free up some bits for another purpose. Paul suggested adding a config option to test the extreme case where the counter is reduced to its minimum usable width for rcutorture to poke at, so do that. Make it only configurable under RCU_EXPERT. While at it, add a comment to explain the layout of context_tracking->state.

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.
