Yeah, maybe checkpath.pl should allow a "Link" after a "Reported-by" for cases like this, then developers could save "Closes" for the patch that addresses the last of the issues the report is about. OTOH checkpatch.pl currently just prints a warning, so developers could ignore this and do the above already now, as you say. Guess it depends on how often we expect "one report with multiple issue" to happen. Maybe this is an indicator that we are on the wrong track in general and should not do any of this and just stick to "Link:". Ciao, Thorsten

This is not specifically a comment about your additional diff, but this sprang to mind (again) while reading it. I have been wondering if this sort of thing will lead to inconsistency. Reports sometimes report more than one issue at once. Other times a patch that is (intentionally) not a complete fix for the problem. Using Closes: in those cases is not really true, as it does not close the report. Having a series of N patches, each of which purport to close an issue, also doesn't seem quite right. The word Closes has a meaning and "forcing" the use of Closes: for reports implies meaning that may not be present. I suppose it is true that just because documentation or checkpatch says to do something, doesn't mean that you **have** to do it but I don't want to be the one on the Rx side of a rant... signature.asc Description: PGP signature

I like your approach of forcing people to use the "Closes:" tag, I didn't think it would have been OK. I will wait a bit before sending a v4 just to get more feedback about that. The good thing with this approach is that it makes things clear. The "Closes:" tag is then no longer an alternative to "Link:" but a different tag, e.g. to be used after "Reported-by" as you did in your patch. I guess as any warnings from checkpatch.pl, it needs to be interpreted, e.g. if multiple bugs are reported in the same report as Conor mentioned.

Maybe it's just me, but I think those changes do not make it clear
enough when to use Link: and when to use Closes. Find below an
alternative proposal how I'd do it for consideration that goes
'all-in' for the sake of simplicity.

[PATCH v3 0/4] docs & checkpatch: allow Closes tags with links
Since v6.3, checkpatch.pl now complains about the use of "Closes:" tags followed by a link [1]. It also complains if a "Reported-by:" tag is followed by a "Closes:" one [2]. As detailed in the first patch, this "Closes:" tag is used for a bit of time, mainly by DRM and MPTCP subsystems. It is used by some bug trackers to automate the closure of issues when a patch is accepted. It is even planned to use this tag with bugzilla.kernel.org [3]. The first patch updates the documentation to explain what is this "Closes:" tag and how/when to use it. The second patch modifies checkpatch.pl to stop complaining about it. The DRM maintainers and their mailing list have been added in Cc as they are probably interested by these two patches as well.

But because it seems that the future Bugzilla bot for kernel.org and regzbot would like to use it as well, I'm sending here new versions. I'm sorry if I misunderstood the comments from v1. Please tell me if I did. Changes in v3: - Patch 1/4 now allow using the "Closes" tag with any kind of bug reports, as long as the link is public. (Thorsten) - The former patch 2/2 has been split in two: first to use a list for the different "link" tags (Joe). Then to allow the 'Closes' tag. - A new patch has been added to let checkpatch.pl checking if "Closes" and "Links" are used with a URL. - Link to v2: https://lore.kernel.org/r/20230314-doc-checkpatch-closes-tag-v2-0-f4a417861...@tessares.net Changes in v2: - The text on patch 1/2 has been reworked thanks to Jon, Bagas and Thorsten.
