The scftorture test can quickly execute a large number of calls to no-wait smp_call_function(), each of which holds a block of memory until the corresponding handler is invoked. Especially when the longwait module parameter is specified, this can chew up an arbitrarily large amount of memory. This commit therefore blocks after each memory-allocation failure, with the duration a function of longwait. 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.
