I'm not the one who's going to apply this, but honestly, I don't think that will
work as a commit message for such a change ...
Sure, link to it by all means, but also summarize it and make sense of it for
the commit message?

Why do you think it will not work ?. There is a long discussion about pros and cons of different approaches by
Page pool maintainers in the discussion link. However I summarize it here, as commit message, it will
Lead to some more questions by reviewers.


I agree with Johannes, this commit message is too thin.

It makes sense to give a summary of the discussion, because it show us
(page_pool maintainers) what you concluded for the discussion.

Further more, you also send another patch:
- "[PATCH net-next] page_pool: Set page pool size"
- https://lore.kernel.org/all/20230809021920.913324-1-rkannoth@xxxxxxxxxxx/

That patch solves the issue for your driver marvell/octeontx2 and I like
than change.

Why did you conclude that PP core should also change?
