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@marvell.com/

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?
