Is the extension of Link: > a new thing? Not really (afaics), but I made that clearer recently. To quote from my own text below: >> This concept is old, but the text was reworked recently to make this use >> case for the Link: tag clearer. For details see: >> https://git.kernel.org/linus/1f57bd42b77c If you search the history, you'll find quite a few commits (some really old) that use 'Link:' to point to bugtracker or regression reports. 'References:' is used as well, but mainly by the drm subsystem. But yes, sadly the Link tag historically is overloaded and used for different things afaics. I'm all for fixing this and plan to start a discussion about this in the next few days (hopefully it doesn't become weeks), but for now I have a few issues with regzbot I need to deal with first.
