If rcutorture is run on a quiet system with the rcutorture.stutter module parameter set high, then there can legitimately be an extended period during which no RCU forward progress takes place. This can result in false-positive no-forward-progress splats. This commit therefore makes rcu_torture_fwd_prog() create a self-propagating RCU callback to ensure that grace periods are in progress for the duration of the forward-progress test. Note that the RCU flavor under test must define ->call(), ->sync(), and ->cb_barrier() for this self-propagating callback to be created. If one or more of those rcu_torture_ops fields are NULL, then the rcu_torture_fwd_prog() function will silently proceed without creating the self-propagating callback. Signed-off-by: Paul E.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
