I don't mind deferring this to the next cycle.

Also, the patches themselves are all written by Jinjiang and me; some of the
descriptions may have been translated or generated with LLM, which helps improve
efficiency for non-native English speakers like me. If you don't like that style,
I'll try to avoid it and write the commit messages manually.

Thanks.

Fine, I'll try but it's not that easy to refactor scan_get_next_rmap_item().
