Someone new to kernel development recently asked how to find review discussion on an upstream patch. And my/other's answer was "search lore for the commit subject", which is a little fussy, and may not help if the subject changed through the reviews.

After the recent Link: tag debate (https://lwn.net/Articles/1037069/), I was thinking if a commit hook was added to insert a Link: tag to a lore query with a sha-like value, one might be able to track all the discussion around a patch's revisions. This seems like it would potentially address Linus' complaint of the commonly used link to the last submission being uninteresting as that's not where the discussion is.

Now, this is obviously similar to Change-Id: tags, so I'd understand the hesitancy, but the hope is it would be immediately useful to everyone rather than Gerrit specific noise.

Has this idea already been considered/shot down?

Maybe answering my own question, looks like Doug sort of had a similar-ish idea, which may be got derailed by the uuid aspect of his suggestion:

@jstultz if it's a patch that is already a commit, you can use "b4 dig" to get all possible information about it, including all revisions we can find. If it's not a commit yet, then we don't currently have a good mechanism to find its history other than what you suggest.
