The rcutorture jitter.sh script selects a random CPU but does not check if it is offline or online. This leads to taskset errors many times. On my machine, hyper threading is disabled so half the cores are offline causing taskset errors a lot of times. Let us fix this by checking from only the online CPUs on the system.

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.
