Currently, if rcu_torture_writer() sees fewer than ten grace periods having elapsed during a call to stutter_wait() that actually waited, the rtort_pipe_count warning is emitted. This has worked well for a long time. Except that the rcutorture TREE07 scenario now does a short-term 14-second RCU CPU stall, which can most definitely case false-positive rtort_pipe_count warnings. This commit therefore changes rcu_torture_writer() to compute the full expected holdoff and stall duration, and to refuse to report any rtort_pipe_count warnings until after all stalls have completed.

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.
