This afaics is missing the following tag:


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:

Apropos regzbot, let me tell regzbot to monitor this thread:

#regzbot ^backmonitor:

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.
