If you need to respin this patch for one reason or another, could you do
me a favor and add proper 'Link:' tags pointing to all reports about
this issue? e.g. like this:

Link:
https://lore.kernel.org/all/Yr7WTfd6AVTQkLjI@xxxxxxxxxxxxxxxxxxxxxxxxxx/

These tags are considered important by Linus[1] and others, as they
allow anyone to look into the backstory weeks or years from now. That is
why they should be placed in cases like this, as
Documentation/process/submitting-patches.rst and
Documentation/process/5.Posting.rst explain in more detail. I care
personally, because these tags make my regression tracking efforts a
whole lot easier, as they allow my tracking bot 'regzbot' to
automatically connect reports with patches posted or committed to fix
tracked regressions.

[1] see for example:
https://lore.kernel.org/all/CAHk-=wjMmSZzMJ3Xnskdg4+GGz=5p5p+GSYyFBTh0f-DgvdBWg@xxxxxxxxxxxxxx/
https://lore.kernel.org/all/CAHk-=wgs38ZrfPvy=nOwVkVzjpM3VFU1zobP37Fwd_h9iAD5JQ@xxxxxxxxxxxxxx/

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.
