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 | 24 ++++++++++++++++++------ 1 file changed, 18 insertions(+), 6 deletions(-) diff --git a/Documentation/process/maintainer-tip.rst b/Documentation/process/maintainer-tip.rst index 64739968afa6..57ffa553c21e 100644 --- a/Documentation/process/maintainer-tip.rst +++ b/Documentation/process/maintainer-tip.rst @@ -375,14 +375,26 @@ following tag ordering scheme: For referring to an email on LKML or other 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 - The kernel.org redirector is considered a stable URL, unlike other email - archives. + This URL should be used when referring to relevant mailing list + resources, related patch sets, or other notable discussion threads. + A convenient way to associate Link trailers with the accompanying + 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.
