Tree RCU supports grace-period delays using the rcutree.gp_cleanup_delay, rcutree.gp_init_delay, and rcutree.gp_preinit_delay kernel boot parameters. These delays are strictly for debugging purposes, and have proven quite effective at exposing bugs involving race with CPU-hotplug operations. However, these delays can result in false positives when used in conjunction with callback flooding, for example, those generated by the rcutorture.fwd_progress kernel boot parameter. This commit therefore suppresses grace-period delays while callback flooding is in progress. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
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.
