27 A patch is a small text document containing a delta of changes between two

33 should both be present in the patch file metadata or be possible to deduce
37 How do I apply or revert a patch?
40 You apply a patch with the ``patch`` program. The patch program reads a diff
41 (or patch) file and makes the changes to the source tree described in it.

77 long, that's a sign that you probably need to split up your patch.
80 When you submit or resubmit a patch or patch series, include the
81 complete patch description and justification for it. Don't just
82 say that this is version N of the patch (series). Don't expect the
83 subsystem maintainer to refer back to earlier patch versions or referenced
84 URLs to find the patch description and put that into the patch.
