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.
