名称描述
move_freepagesMove the free pages in a range to the free lists of the requested type.* Note that start_page and end_pages are not aligned on a pageblock* boundary. If alignment is required, use move_freepages_block()
steal_suitable_fallbackThis function implements actual steal behaviour. If order is large enough,* we can steal whole pageblock. If not, we first move freepages in this* pageblock to our migratetype and determine how many already-allocated pages
