[PATCH v3 04/16] mm/balloon: use general movable page feature into balloon
...PageBalloon(struct page *page) > +{ > + return atomic_read(&page->_mapcount) == PAGE_BALLOON_MAPCOUNT_VALUE > + && PagePrivate2(page); > +} Hmm so you are now using PG_private_2 flag here, but it's not documented. Also the only caller of PageBalloon() seems to be stable_page_flags(). Which will now report all movable pages with PG_private_2 as KPF_BALOON. Seems like an overkill and also not reliable. Could it test e.g. page->mapping instead? Or maybe if we manage to get rid of PAGE_MOVABLE_MAPCOUNT_VALUE, we can keep PAGE_BALLOON_MAPCOUNT_VALUE to simply distinguish b...
