The torture_stutter() function uses schedule_timeout_interruptible() to time the stutter duration, but this can miss race conditions due to its being time-synchronized with everything else that is based on the timer wheels. This commit therefore converts torture_stutter() to use the high-resolution timers via schedule_hrtimeout(), and also to fuzz the stutter interval. While in the area, this commit also limits the spin-loop portion of the stutter_wait() function's wait loop to two jiffies, down from about one second. 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.
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.
