Additional rcutorture aggression can result in, believe it or not, boot times in excess of three minutes on large hyperthreaded systems. This is long enough for rcutorture to decide to do some callback flooding, which seems a bit excessive given that userspace cannot have started until long after boot, and it is userspace that does the real-world callback flooding. Worse yet, because Tiny RCU lacks forward-progress functionality, the looping-in-the-kernel tests can also be problematic during early boot. This commit therefore causes rcutorture to hold off on callback flooding until about the time that init is spawned, and the same for looping-in-the-kernel tests for Tiny RCU. 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.
