Based on multiple conversations, most recently on the ksummit mailing list [1], add some best practices for using the Link trailer, such as: - how to use markdown-like bracketed numbers in the commit message to indicate the corresponding link - when to use lore.kernel.org vs patch.msgid.link domains Cc: ksummit@xxxxxxxxxxxxxxx Link: https://lore.kernel.org/20240617-arboreal-industrious-hedgehog-5b84ae@meerkat # [1] Signed-off-by: Konstantin Ryabitsev <konstantin@xxxxxxxxxxxxxxxxxxx> --- Documentation/process/maintainer-tip.rst | 30 ++++++++++++++++++++++-------- 1 file changed, 22 insertions(+), 8 deletions(-) diff --git a/Documentation/process/maintainer-tip.rst b/Documentation/process/maintainer-tip.rst index 64739968afa6..ba312345d030 100644 --- a/Documentation/process/maintainer-tip.rst +++ b/Documentation/process/maintainer-tip.rst @@ -372,17 +372,31 @@ following tag ordering scheme: - Link: ``https://link/to/information`` - For referring to an email on LKML or other kernel mailing lists, - please use the lore.kernel.org redirector URL:: + For referring to an email posted to the kernel mailing lists, please + use the lore.kernel.org redirector URL:: - https://lore.kernel.org/r/email-message@id + Link: https://lore.kernel.org/email-message-id@here - The kernel.org redirector is considered a stable URL, unlike other email - archives. + This URL should be used when referring to relevant mailing list + topics, related patch sets, or other notable discussion threads. + A convenient way to associate ``Link:`` trailers with the commit + message is to use markdown-like bracketed notation, for example:: - Maintainers will add a Link tag referencing the email of the patch - submission when they apply a patch to the tip tree.
