If a callback flood prevents grace period from completing, rcutorture does a WARN_ON(). Avoiding this WARN_ON() currently requires that at least three grace periods elapse during an eight-second callback-flood interval. Unfortunately, the current debug information does not include anything about the grace-period state. This commit therefore adds a call to cur_ops->gp_kthread_dbg(), if this function pointer is non-NULL. 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 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.
