This tag is useful - for later reference and is also used for commit notifications. + A similar approach was attempted before as part of a different + effort [1], but the initial implementation caused too many + regressions [2], so it was backed out and reimplemented. + + Link: https://lore.kernel.org/some-msgid@here # [1] + Link: https://bugzilla.example.org/bug/12345 # [2] + + You can also use ``Link:`` trailers to indicate the origin of the + patch when applying it to your git tree. In that case, please use the + dedicated ``patch.msgid.link`` domain instead of ``lore.kernel.org``. + This practice makes it possible for automated tooling to identify + which link to use to retrieve the original patch submission. For + example:: + + Link: https://patch.msgid.link/patch-source-message-id@here Please do not use combined tags, e.g. ``Reported-and-tested-by``, as they just complicate automated extraction of tags.
