This is an unfortunate software situation.

How do you think about to omit this sentence from the change description?

I suggest to convert this information into an imperative wording.
Would you like to add the tag “Fixes” to the commit message?
Regards,
Markus

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
