documentation mechanism based on the Sphinx system. The objectives here are to make it easier to create better-integrated (and more attractive) documents while (eventually) dumping our one-of-a-kind, cobbled-together system for something that is widely used and maintained by others. There's a fair amount of information what's being done, why, and how to use it in: https://lwn.net/Articles/692704/ https://lwn.net/Articles/692705/ Closer to home, Documentation/kernel-documentation.rst describes how it works. For now, the new system exists alongside the old one; you should soon see the GPU documentation converted over in the DRM pull and some significant media conversion work as well. Once all the docs have been moved over and we're convinced that the rough edges (of which are are a few) have been smoothed over, the DocBook-based stuff should go away. Primary credit is to Jani Nikula for doing the heavy lifting to make this stuff actually work; there has also been notable effort from Markus Heiser, Daniel Vetter, and Mauro Carvalho Chehab. Expect a couple of conflicts on the new index.rst file over the course of the merge window; they are trivially resolvable. That file may be a bit of a conflict magnet in the short term, but I don't expect that situation to last for any real length of time. Beyond that, of course, we have the usual collection of tweaks, updates, and typo fixes. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJXlT8bAAoJEI3ONVYwIuV6IF0QAM7qpEgAveXgwzGr18ReftjB ryyPXdLNX8R7fQkUAu85Znlw93k4+7QxHseBgZ1I3t9IhjvzemidOKfj96SJ0DVE zco5FUTO1TPfO2uG8asNzlXSrwktrEZoFTraRIYpCjAAimg/UEQAM4xgNOJfmW39 8eLg6dhnzqnfCH6M+Q7AZPLmqNSOfA2qNFqHNs7VCbwjLQC0l4yw4PHOsdX0QhCL NtlukHOhB4CwaELDl6lZOQgnz79e4pDljFd/wA/vVpdq7ev8NnOgVVt93M2fUvLX Bdfzo2OtZg7LJnWtpQl2LJq2MJJdOmgIw+ls6cB5gvxV3+CCIndE/6IIbimC/lZi DiaaqVU/EV3AemBDbqErO4k3ZvMT2ZTaSx1OQoLpIwNAsAkEOkb+t2hcwrTqhxg1 kEIXEEboXwStBtH3iar2YiGHQWUhia4mxfv5n4Dvamaca4tGWXHWxSRjbRcaJ1ef v1kt6ymjwr2sd9116EUxngfYONwlrhk5F87D/dC2eQzEyS0z7+F8wWb/h2gsAaU1 6oVCoQjTe2KAc/7dHINMSIjg2TfVfHS5XIhWu5z6wyxRb8ey9QuKLQYlOTV/L3Ms aR4O6qvDIsIbOvEd+hHSIbeG7JOPd0LdSI4tdo4d9kquW2OJ6TmmOr/ihbJt430v s/Qxqwgme/8DJd3KcV6j =4fDK -----END PGP SIGNATURE----- Merge tag 'docs-for-linus' of git://git.lwn.net/linux Pull documentation updates from Jonathan Corbet: "Some big changes this month, headlined by the addition of a new formatted documentation mechanism based on the Sphinx system.

Documentation for /proc/sys/ kernel version 2.2.10 (c) 1998, 1999, Rik van Riel <riel@nl.linux.org> 'Why', I hear you ask, 'would anyone even _want_ documentation for them sysctl files? If anybody really needs it, it's all in the source...' Well, this documentation is written because some people either don't know they need to tweak something, or because they don't have the time or knowledge to read the source code. Furthermore, the programmers who built sysctl have built it to be actually used, not just for the fun of programming it :-) ============================================================== Legal blurb: As usual, there are two main things to consider: 1. you get what you pay for 2. it's free The consequences are that I won't guarantee the correctness of this document, and if you come to me complaining about how you screwed up your system because of wrong documentation, I won't feel sorry for you. I might even laugh at you... But of course, if you _do_ manage to screw up your system using only the sysctl options used in this file, I'd like to hear of it. Not only to have a great laugh, but also to make sure that you're the last RTFMing person to screw up. In short, e-mail your suggestions, corrections and / or horror stories to: <riel@nl.linux.org> Rik van Riel. ============================================================== Introduction: Sysctl is a means of configuring certain aspects of the kernel at run-time, and the /proc/sys/ directory is there so that you don't even need special tools to do it! In fact, there are only four things needed to use these config facilities: - a running Linux system - root access - common sense (this is especially hard to come by these days) - knowledge of what all those values mean As a quick 'ls /proc/sys' will show, the directory consists of several (arch-dependent?) subdirs. Each subdir is mainly about one part of the kernel, so you can do configuration on a piece by piece basis, or just some 'thematic frobbing'. The subdirs are about: abi/ execution domains & personalities debug/ <empty> dev/ device specific information (eg dev/cdrom/info) fs/ specific filesystems filehandle, inode, dentry and quota tuning binfmt_misc <Documentation/binfmt_misc.txt> kernel/ global kernel info / tuning miscellaneous stuff net/ networking stuff, for documentation look in: <Documentation/networking/> proc/ <empty> sunrpc/ SUN Remote Procedure Call (NFS) vm/ memory management tuning buffer and cache management These are the subdirs I have on my system. There might be more or other subdirs in another setup. If you see another dir, I'd really like to hear about it :-)
