I think checkpatch is pretty good about cc'ing mostly the right folk by default. Where it's not adequate is when some particular bit of code was written by someone not the maintainer and that writer should also be copied on a patch. Many different command-line options exist for get_maintainer. Perhaps too many. --git-blame can be used with patches to also list the author of any modified commit. Using that option can take a fairly long while to run though. > Their output is not always correct, and some amount of human common > sense is required. True.

There is no good solution to this problem. You can't cc the world on patch 1/n (vger rejects emails with too many recipients) and cc just the maintainers on x/n. One solution is to send the 0/n and 1/n patches to all the email lists that are cc'd on any single patch of large patch series. A better solution might be to send _only_ the 1/n patch to lkml and to someone like Andrew Morton with an explanation as to why it's useful, wait for it to be applied, then send the large patch series during the next release cycle. > There's a reason why many developers cordially hate these scripts; > it's too easy to misuse them, Yup, though cordial can be a misdescription for some of those developers...
