[PATCH RFC] Docs: Modernize SubmittingPatches
From: Jonathan Corbet
Date: Mon Dec 15 2014 - 10:53:05 EST
The SubmittingPatches file still shows a lot of its roots from the era when
we all sent stuff straight to Linus and hoped for the best. I've gone in
and thrashed it up to reflect an age where few of us type our own "diff"
commands anymore. Also added a section on preparing signed tags for pull
requests.

SECTION 1 - CREATING AND SENDING YOUR CHANGE

+0) Obtain a current source tree
+-------------------------------

+If you do not have a repository with the current kernel source handy, use
+git to obtain one. You'll want to start with the mainline repository,
+which can be grabbed with:
+
+ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
+
+Note, however, that you may not want to develop against the mainline tree
+directly. Most subsystem maintainers run their own trees and want to see
+patches prepared against those trees. See the "T:" entry for the subsystem
+in the MAINTAINERS file to find that tree, or simply ask the maintainer if
+the tree is not listed there.

+It is still possible to download kernel releases via tarballs (as described
+in the next section), but that is the hard way to do kernel development.

-submitted to the kernel. There are always exceptions... but you must
-have a really good reason for doing so. You could probably call this
-section Linus Computer Science 101.
-
-
-
-1) Read Documentation/CodingStyle
-
-Nuff said. If your code deviates too much from this, it is likely
-to be rejected without further review, and without comment.
-
-One significant exception is when moving code from one file to
-another -- in this case you should not modify the moved code at all in
-the same patch which moves it. This clearly delineates the act of
-moving the code and your changes. This greatly aids review of the
-actual differences and allows tools to better track the history of
-the code itself.
-
-Check your patches with the patch style checker prior to submission
-(scripts/checkpatch.pl). The style checker should be viewed as
-a guide not as the final word. If your code looks better with
-a violation then its probably best left alone.
-
-The checker reports at three levels:
- - ERROR: things that are very likely to be wrong
- - WARNING: things requiring careful review
- - CHECK: things requiring thought
-
-You should be able to justify all violations that remain in your
-patch.
-
-
-
-2) #ifdefs are ugly
-
-Code cluttered with ifdefs is difficult to read and maintain. Don't do
-it. Instead, put your ifdefs in a header, and conditionally define
-'static inline' functions, or macros, which are used in the code.
-Let the compiler optimize away the "no-op" case.
-
-Simple example, of poor code:
-
- dev = alloc_etherdev (sizeof(struct funky_private));
- if (!dev)
- return -ENODEV;
- #ifdef CONFIG_NET_FUNKINESS
- init_funky_net(dev);
- #endif
-
-Cleaned-up example:

+-------------------------------
-(in the code itself)
- dev = alloc_etherdev (sizeof(struct funky_private));
- if (!dev)
- return -ENODEV;
- init_funky_net(dev);
+If you have a series of patches, it may be most convenient to have the
+maintainer pull them directly into the subsystem repository with a
+"git pull" operation. Note, however, that pulling patches from a developer
+requires a higher degree of trust than taking patches from a mailing list.
+As a result, many subsystem maintainers are reluctant to take pull
+requests, especially from new, unknown developers.
+A pull request should have [GIT] or [PULL] in the subject line. The
+request itself should include the repository name and the branch of
+interest on a single line; it should look something like:
+ Please pull from
-3) 'static inline' is better than a macro
+ git://jdelvare.pck.nerim.net/jdelvare-2.6 i2c-for-linus
-Static inline functions are greatly preferred over macros.
-They provide type safety, have no length limitations, no formatting
-limitations, and under gcc they are as cheap as macros.
+ to get these changes:"
-Macros should only be used for cases where a static inline is clearly
-suboptimal [there are a few, isolated cases of this in fast paths],
-or where it is impossible to use a static inline function [such as
-string-izing].
+A pull request should also include an overall message saying what will be
+included in the request, a "git shortlog" listing of the patches
+themselves, and a diffstat showing the overall effect of the patch series.
+The easiest way to get all this information together is, of course, to let
+git do it for you with the "git request-pull" command.
-'static inline' is preferred over 'static __inline__', 'extern inline',
-and 'extern __inline__'.
+Some maintainers (including Linus) want to see pull requests from signed
+commits; that increases their confidence that the request actually came
+from you. Linus, in particular, will not pull from public hosting sites
+like GitHub in the absence of a signed tag.
+The first step toward creating such tags is to make a GNUPG key and get it
+signed by one or more core kernel developers. This step can be hard for
+new developers, but there is no way around it. Attending conferences can
+be a good way to find developers who can sign your key.
+Once you have prepared a patch series in git that you wish to have somebody
+pull, create a signed tag with "git tag -s". This will create a new tag
+identifying the last commit in the series and containing a signature
+created with your private key. You will also have the opportunity to add a
+changelog-style message to the tag; this is an ideal place to describe the
+effects of the pull request as a whole.
-4) Don't over-design.
+If the tree the maintainer will be pulling from is not the repository you
+are working from, don't forget to push the signed tag explicitly to the
+public tree.
