Once removed, an rcu_torture element can be deferred-freed by a chain of call_rcu() invocations, with each callback invoking another round of call_rcu() until either a fixed number of call_rcu() invocations have been chained or until the test ends. This means that if the test ends, some of the rcu_torture elements will be "stranded" partway through the deferred-free process, which results in false-positive warnings from rcu_torture_writer() due to lack of forward progress should the test end just at the end of a stutter interval. This commit therefore suppresses rcu_torture_writer()'s forward-progress checks when the test ends in order to avoid these false-positive reports..

README
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.
