   3        List of maintainers and how to submit kernel changes
   4
   5Please try to follow the guidelines below.  This will make things
   6easier on the maintainers.  Not all of these guidelines matter for every
   7trivial patch so apply some common sense.
   8
   91.      Always _test_ your changes, however small, on at least 4 or
  10        5 people, preferably many more.
  11
  122.      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
  203.      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
  244.      When you are happy with a change make it generally available for
  25        testing and await feedback.
  26
  275.      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
  596.      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
  637.      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
  758.      Happy hacking.

  77Descriptions 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
 131Note: For the hard of thinking, this list is meant to remain in alphabetical
 132order. If you could add yourselves to it in alphabetical order that would be
 133so much easier [Ed]
