If we are to officially encourage the use of checkpatch.pl, we should stress that mechanically adhering to its check is *not* the goal. As long as people view it as a tool to _help_ them spot obvious problems before sending their patches out, but the final responsibility to produce readable code is upon themselves, not the script, I am personally fine. Oftentimes we find an occasional long line that is slightly longer than 80-column limit a lot easier to read than chopping it artificially in the middle, for example. >> 2.

Not really. Maintaining the forked version is an additional pain we do not necessarily need. Are we going to carry a port of gcc and others? I would rather prefer to add a paragraph in CodingGuidelines that points at the canonical location to obtain the script, e.g. https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/scripts/checkpatch.pl and a procedure to run the script over their patch. I am too lazy to check myself, but there must be somewhere we mention the use of format-patch and send-email in the document, and use of the script to check would fall naturally between these two steps, I would think. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I've never said any such thing. I only said I am not enthused against a proposal to add a build target that runs checkpatch or equivalent over *all* existing code, which will invite needless churn (read again the part of the message you quoted before I say "I am not enthused"). It is a totally separate issue for submitters to make sure they do not introduce *new* problems, and use of "checkpatch --no-tree" could be one way to do so. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
