Will the attention grow for the application of “imperative mood”
in change descriptions?

How do you think about to add the tag “Fixes”?

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst?h=v6.5-rc3#n145


Would any other subject become more appropriate for your patch?

Hi,

This is the semi-friendly patch-bot of Greg Kroah-Hartman.

Markus, you seem to have sent a nonsensical or otherwise pointless
review comment to a patch submission on a Linux kernel developer mailing
list.  I strongly suggest that you not do this anymore.  Please do not
bother developers who are actively working to produce patches and
features with comments that, in the end, are a waste of time.

Patch submitter, please ignore Markus's suggestion; you do not need to
follow it at all.  The person/bot/AI that sent it is being ignored by
almost all Linux kernel maintainers for having a persistent pattern of
behavior of producing distracting and pointless commentary, and
inability to adapt to feedback.  Please feel free to also ignore emails
from them.

thanks,

greg k-h's patch email bot

I hope that the “intelligence” can be improved also for this software component.

This automated response is a questionable side effect of known
recurring communication difficulties, isn't it?


> Patch submitter, please ignore Markus's suggestion; you do not need to

…

I hope that this request will be reconsidered in more detail
especially when my change suggestions can be interpreted as reminders
from the Linux development documentation for a discussed patch.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst?h=v6.5-rc3#n3

Will the chances ever grow to resolve affected aspects in more constructive ways?

Regards,
Markus
