Linux kernel source tree

Contrary to other tests, test_find_next_and_bit() test uses tab formatting in output and get_cycles() instead of ktime_get(). get_cycles() is not supported by some arches, so ktime_get() fits better in generic code. Fix it and minor style issues, so the output looks like this: Start testing find_bit() with random-filled bitmap find_next_bit: 7142816 ns, 163282 iterations find_next_zero_bit: 8545712 ns, 164399 iterations find_last_bit: 6332032 ns, 163282 iterations find_first_bit: 20509424 ns, 16606 iterations find_next_and_bit: 4060016 ns, 73424 iterations Start testing find_bit() with sparse bitmap find_next_bit: 55984 ns, 656 iterations find_next_zero_bit: 19197536 ns, 327025 iterations find_last_bit: 65088 ns, 656 iterations find_first_bit: 5923712 ns, 656 iterations find_next_and_bit: 29088 ns, 1 iterations Link: http://lkml.kernel.org/r/20181123174803.10916-1-ynorov@caviumnetworks.com Signed-off-by: Yury Norov <ynorov@caviumnetworks.com> Reviewed-by: Andrew Morton <akpm@linux-foundation.org> Cc: "Norov, Yuri" <Yuri.Norov@cavium.com> Cc: Clement Courbet <courbet@google.com> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: Alexey Dobriyan <adobriyan@gmail.com> Cc: Matthew Wilcox <mawilcox@microsoft.com> Cc: Rasmus Villemoes <linux@rasmusvillemoes.dk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.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.
