   3         List of maintainers and how to submit kernel changes
   4
   5 Please try to follow the guidelines below.  This will make things
   6 easier on the maintainers.  Not all of these guidelines matter for every
   7 trivial patch so apply some common sense.
   8
   9 1.      Always _test_ your changes, however small, on at least 4 or
  10         5 people, preferably many more.
  11
  12 2.      Try to release a few ALPHA test versions to the net. Announce
  13         them onto the kernel channel and await results. This is especially
  14         important for device drivers, because often that's the only way
  15         you will find things like the fact version 3 firmware needs
  16         a magic fix you didn't know about, or some clown changed the
  17         chips on a board and not its name.  (Don't laugh!  Look at the
  18         SMC etherpower for that.)
  19
  20 3.      Make sure your changes compile correctly in multiple
  21         configurations. In particular check that changes work both as a
  22         module and built into the kernel.
  23
  24 4.      When you are happy with a change make it generally available for
  25         testing and await feedback.
  26
  27 5.      Make a patch available to the relevant maintainer in the list. Use
  28         'diff -u' to make the patch easy to merge. Be prepared to get your
  29         changes sent back with seemingly silly requests about formatting
  30         and variable names.  These aren't as silly as they seem. One
  31         job the maintainers (and especially Linus) do is to keep things
  32         looking the same. Sometimes this means that the clever hack in
  33         your driver to get around a problem actually needs to become a
  34         generalized kernel feature ready for next time.
  35
  36         PLEASE check your patch with the automated style checker
  37         (scripts/checkpatch.pl) to catch trivial style violations.
  38         See Documentation/process/coding-style.rst for guidance here.
  39
  40         PLEASE CC: the maintainers and mailing lists that are generated
  41         by scripts/get_maintainer.pl.  The results returned by the
  42         script will be best if you have git installed and are making
  43         your changes in a branch derived from Linus' latest git tree.
  44         See Documentation/process/submitting-patches.rst for details.
  45
  46         PLEASE try to include any credit lines you want added with the
  47         patch. It avoids people being missed off by mistake and makes
  48         it easier to know who wants adding and who doesn't.
  49
  50         PLEASE document known bugs. If it doesn't work for everything
  51         or does something very odd once a month document it.
  52
  53         PLEASE remember that submissions must be made under the terms
  54         of the Linux Foundation certificate of contribution and should
  55         include a Signed-off-by: line.  The current version of this
  56         "Developer's Certificate of Origin" (DCO) is listed in the file
  57         Documentation/process/submitting-patches.rst.
  58
  59 6.      Make sure you have the right to send any changes you make. If you
  60         do changes at work you may find your employer owns the patch
  61         not you.
  62
  63 7.      When sending security related changes or reports to a maintainer
  64         please Cc: security@kernel.org, especially if the maintainer
  65         does not respond. Please keep in mind that the security team is
  66         a small set of people who can be efficient only when working on
  67         verified bugs. Please only Cc: this list when you have identified
  68         that the bug would present a short-term risk to other users if it
  69         were publicly disclosed. For example, reports of address leaks do
  70         not represent an immediate threat and are better handled publicly,
  71         and ideally, should come with a patch proposal. Please do not send
  72         automated reports to this list either. Such bugs will be handled
  73         better and faster in the usual public places.
  74
  75 8.      Happy hacking.
  76
  77 Descriptions of section entries:
  78
  79         P: Person (obsolete)
  80         M: Mail patches to: FullName <address@domain>
  81         R: Designated reviewer: FullName <address@domain>
  82            These reviewers should be CCed on patches.
  83         L: Mailing list that is relevant to this area
  84         W: Web-page with status/info
  85         B: URI for where to file bugs. A web-page with detailed bug
  86            filing info, a direct bug tracker link, or a mailto: URI.
  87         C: URI for chat protocol, server and channel where developers
  88            usually hang out, for example irc://server/channel.
  89         Q: Patchwork web based patch tracking system site
  90         T: SCM tree type and location.
  91            Type is one of: git, hg, quilt, stgit, topgit
  92         S: Status, one of the following:
  93            Supported:   Someone is actually paid to look after this.
  94            Maintained:  Someone actually looks after it.
  95            Odd Fixes:   It has a maintainer but they don't have time to do
  96                         much other than throw the odd patch in. See below..
  97            Orphan:      No current maintainer [but maybe you could take the
  98                         role as you write your new code].
  99            Obsolete:    Old code. Something tagged obsolete generally means
 100                         it has been replaced by a better system and you
 101                         should be using that.
 102         F: Files and directories with wildcard patterns.
 103            A trailing slash includes all files and subdirectory files.
 104            F:   drivers/net/    all files in and below drivers/net
 105            F:   drivers/net/*   all files in drivers/net, but not below
 106            F:   */net/*         all files in "any top level directory"/net
 107            One pattern per line.  Multiple F: lines acceptable.
 108         N: Files and directories with regex patterns.
 109            N:   [^a-z]tegra     all files whose path contains the word tegra
 110            One pattern per line.  Multiple N: lines acceptable.
 111            scripts/get_maintainer.pl has different behavior for files that
 112            match F: pattern and matches of N: patterns.  By default,
 113            get_maintainer will not look at git log history when an F: pattern
 114            match occurs.  When an N: match occurs, git log history is used
 115            to also notify the people that have git commit signatures.
 116         X: Files and directories that are NOT maintained, same rules as F:
 117            Files exclusions are tested before file matches.
 118            Can be useful for excluding a specific subdirectory, for instance:
 119            F:   net/
 120            X:   net/ipv6/
 121            matches all files in and below net excluding net/ipv6/
 122         K: Keyword perl extended regex pattern to match content in a
 123            patch or file.  For instance:
 124            K: of_get_profile
 125               matches patches or files that contain "of_get_profile"
 126            K: \b(printk|pr_(info|err))\b
 127               matches patches or files that contain one or more of the words
 128               printk, pr_info or pr_err
 129            One regex pattern per line.  Multiple K: lines acceptable.
 130
 131 Note: For the hard of thinking, this list is meant to remain in alphabetical
 132 order. If you could add yourselves to it in alphabetical order that would be
 133 so much easier [Ed]
