1List of maintainers and how to submit kernel changes
2====================================================
3
4Please try to follow the guidelines below.  This will make things
5easier on the maintainers.  Not all of these guidelines matter for every
6trivial patch so apply some common sense.
7
8Tips for patch submitters
9-------------------------
10
111.	Always *test* your changes, however small, on at least 4 or
12	5 people, preferably many more.
13
142.	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
223.	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
264.	When you are happy with a change make it generally available for
27	testing and await feedback.
28
295.	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
616.	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
657.	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
788.	Happy hacking.

80Descriptions 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.
