171 PG_movable不是struct page的一个真正的标志。相反，VM复用了page->mapping的低
175 page->mapping = page->mapping | PAGE_MAPPING_MOVABLE;
177 所以驱动不应该直接访问page->mapping。相反，驱动应该使用page_mapping()，它可
178 以在页面锁下屏蔽掉page->mapping的低2位，从而获得正确的struct address_space。
181 非LRU可移动页面，因为page->mapping字段与struct page中的其他变量是统一的。如
182 果驱动程序在被虚拟机隔离后释放了页面，尽管page->mapping设置了PAGE_MAPPING_MOVABLE，
185 page->mapping中不可能有PAGE_MAPPING_MOVABLE设置。在用pfn扫描中的lock_page()
