Patch series "mm: Generalize putback functions"] putback_inactive_pages() and move_active_pages_to_lru() are almost similar, so this patchset merges them ina single function. This patch (of 4): The patch moves the calculation from putback_inactive_pages() to shrink_inactive_list(). This makes putback_inactive_pages() looking more similar to move_active_pages_to_lru(). To do that, we account activated pages in reclaim_stat::nr_activate. Since a page may change its LRU type from anon to file cache inside shrink_page_list() (see ClearPageSwapBacked()), we have to account pages for the both types. So, nr_activate becomes an array. Previously we used nr_activate to account PGACTIVATE events, but now we account them into pgactivate variable (since they are about number of pages in general, not about sum of hpage_nr_pages).
