* page->lru: links together first pages of various zspages.
* Basically forming list of zspages in a fullness group.
* page->mapping: class index and fullness group of the zspage
+ * page->inuse: the number of objects that are used in this zspage
*
* Usage of struct page flags:
* PG_private: identifies the first component page
