MAINTAINERS

   1 List of maintainers and how to submit kernel changes
   2 ====================================================
   3
   4 Please try to follow the guidelines below.  This will make things
   5 easier on the maintainers.  Not all of these guidelines matter for every
   6 trivial patch so apply some common sense.
   7
   8 Tips for patch submitters
   9 -------------------------
  10
  11 1.      Always *test* your changes, however small, on at least 4 or
  12         5 people, preferably many more.
  13
  14 2.      Try to release a few ALPHA test versions to the net. Announce
  15         them onto the kernel channel and await results. This is especially
  16         important for device drivers, because often that's the only way
  17         you will find things like the fact version 3 firmware needs
  18         a magic fix you didn't know about, or some clown changed the
  19         chips on a board and not its name.  (Don't laugh!  Look at the
  20         SMC etherpower for that.)
  21
  22 3.      Make sure your changes compile correctly in multiple
  23         configurations. In particular check that changes work both as a
  24         module and built into the kernel.
  25
  26 4.      When you are happy with a change make it generally available for
  27         testing and await feedback.
  28
  29 5.      Make a patch available to the relevant maintainer in the list. Use
  30         ``diff -u`` to make the patch easy to merge. Be prepared to get your
  31         changes sent back with seemingly silly requests about formatting
  32         and variable names.  These aren't as silly as they seem. One
  33         job the maintainers (and especially Linus) do is to keep things
  34         looking the same. Sometimes this means that the clever hack in
  35         your driver to get around a problem actually needs to become a
  36         generalized kernel feature ready for next time.
  37
  38         PLEASE check your patch with the automated style checker
  39         (scripts/checkpatch.pl) to catch trivial style violations.
  40         See Documentation/process/coding-style.rst for guidance here.
  41
  42         PLEASE CC: the maintainers and mailing lists that are generated
  43         by ``scripts/get_maintainer.pl.`` The results returned by the
  44         script will be best if you have git installed and are making
  45         your changes in a branch derived from Linus' latest git tree.
  46         See Documentation/process/submitting-patches.rst for details.
  47
  48         PLEASE try to include any credit lines you want added with the
  49         patch. It avoids people being missed off by mistake and makes
  50         it easier to know who wants adding and who doesn't.
  51
  52         PLEASE document known bugs. If it doesn't work for everything
  53         or does something very odd once a month document it.
  54
  55         PLEASE remember that submissions must be made under the terms
  56         of the Linux Foundation certificate of contribution and should
  57         include a Signed-off-by: line.  The current version of this
  58         "Developer's Certificate of Origin" (DCO) is listed in the file
  59         Documentation/process/submitting-patches.rst.
  60
  61 6.      Make sure you have the right to send any changes you make. If you
  62         do changes at work you may find your employer owns the patch
  63         not you.
  64
  65 7.      When sending security related changes or reports to a maintainer
  66         please Cc: security@kernel.org, especially if the maintainer
  67         does not respond. Please keep in mind that the security team is
  68         a small set of people who can be efficient only when working on
  69         verified bugs. Please only Cc: this list when you have identified
  70         that the bug would present a short-term risk to other users if it
  71         were publicly disclosed. For example, reports of address leaks do
  72         not represent an immediate threat and are better handled publicly,
  73         and ideally, should come with a patch proposal. Please do not send
  74         automated reports to this list either. Such bugs will be handled
  75         better and faster in the usual public places. See
  76         Documentation/admin-guide/security-bugs.rst for details.
  77
  78 8.      Happy hacking.

  80 Descriptions of section entries and preferred order
  81 ---------------------------------------------------
  82
  83         M: *Mail* patches to: FullName <address@domain>
  84         R: Designated *Reviewer*: FullName <address@domain>
  85            These reviewers should be CCed on patches.
  86         L: *Mailing list* that is relevant to this area
  87         S: *Status*, one of the following:
  88            Supported:   Someone is actually paid to look after this.
  89            Maintained:  Someone actually looks after it.
  90            Odd Fixes:   It has a maintainer but they don't have time to do
  91                         much other than throw the odd patch in. See below..
  92            Orphan:      No current maintainer [but maybe you could take the
  93                         role as you write your new code].
  94            Obsolete:    Old code. Something tagged obsolete generally means
  95                         it has been replaced by a better system and you
  96                         should be using that.
  97         W: *Web-page* with status/info
  98         Q: *Patchwork* web based patch tracking system site
  99         B: URI for where to file *bugs*. A web-page with detailed bug
 100            filing info, a direct bug tracker link, or a mailto: URI.
 101         C: URI for *chat* protocol, server and channel where developers
 102            usually hang out, for example irc://server/channel.
 103         P: Subsystem Profile document for more details submitting
 104            patches to the given subsystem. This is either an in-tree file,
 105            or a URI. See Documentation/maintainer/maintainer-entry-profile.rst
 106            for details.
 107         T: *SCM* tree type and location.
 108            Type is one of: git, hg, quilt, stgit, topgit
 109         F: *Files* and directories wildcard patterns.
 110            A trailing slash includes all files and subdirectory files.
 111            F:   drivers/net/    all files in and below drivers/net
 112            F:   drivers/net/*   all files in drivers/net, but not below
 113            F:   */net/*         all files in "any top level directory"/net
 114            One pattern per line.  Multiple F: lines acceptable.
 115         X: *Excluded* files and directories that are NOT maintained, same
 116            rules as F:. Files exclusions are tested before file matches.
 117            Can be useful for excluding a specific subdirectory, for instance:
 118            F:   net/
 119            X:   net/ipv6/
 120            matches all files in and below net excluding net/ipv6/
 121         N: Files and directories *Regex* patterns.
 122            N:   [^a-z]tegra     all files whose path contains tegra
 123                                 (not including files like integrator)
 124            One pattern per line.  Multiple N: lines acceptable.
 125            scripts/get_maintainer.pl has different behavior for files that
 126            match F: pattern and matches of N: patterns.  By default,
 127            get_maintainer will not look at git log history when an F: pattern
 128            match occurs.  When an N: match occurs, git log history is used
 129            to also notify the people that have git commit signatures.
 130         K: *Content regex* (perl extended) pattern match in a patch or file.
 131            For instance:
 132            K: of_get_profile
 133               matches patches or files that contain "of_get_profile"
 134            K: \b(printk|pr_(info|err))\b
 135               matches patches or files that contain one or more of the words
 136               printk, pr_info or pr_err
 137            One regex pattern per line.  Multiple K: lines acceptable.
