On v7 Jakub asked [1] [2] few questions about the patch series
and I answered [3].

[1] https://lore.kernel.org/linux-mm/20250626174904.4a6125c9@kernel.org
[2] https://lore.kernel.org/linux-mm/20250627173730.15b25a8c@kernel.org

To me Jakub's comment "Thanks a lot, this clarifies things for me"
and still "hard to judge patches 1 and 7 in context limited to this series"
after reading my clarification (which wasn't part of the series)
sounded like he wants some of the clarification to be added to
later versions of the patchset.

But I don't speak for Jakub, I'll leave the answer to him.
Maybe I just misinterpreted his reply.
