mm/vmscan: convert reclaim_clean_pages_from_list() to folios
Patch series "nvert much of vmscan to folios"
vmscan always operates on folios since it puts the pages on the LRU list.
Switching all of these functions from pages to folios saves 1483 bytes of
text from removing all the baggage around calling compound_page() and
similar functions.
This patch (of 5):
This is a straightforward conversion which removes several hidden calls
to compound_head, saving 330 bytes of kernel text.
