If there is a large number of torture tests running concurrently, all of which are dumping large ftrace buffers at shutdown time, the resulting dumping can take a very long time, particularly on systems with rotating-rust storage. This commit therefore adds a default-off torture.ftrace_dump_at_shutdown module parameter that enables shutdown-time ftrace-buffer dumping. 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.
