It measures the total time taken by fns() to process 10,000 test data generated using get_random_bytes() for each n in the range [0, BITS_PER_LONG). example: test_bitops: fns: 7637268 ns CC: Andrew Morton <akpm@linux-foundation.org> CC: Rasmus Villemoes <linux@rasmusvillemoes.dk> CC: David Laight <David.Laight@aculab.com> Signed-off-by: Kuan-Wei Chiu <visitorckw@gmail.com> Suggested-by: Yury Norov <yury.norov@gmail.com> Signed-off-by: Yury Norov <yury.norov@gmail.com>
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 reStructuredText 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.
