mm: convert ksm_might_need_to_copy() to work on folios
Patch series "Finish two folio conversions".
Most callers of page_add_new_anon_rmap() and
lru_cache_add_inactive_or_unevictable() have been converted to their folio
equivalents, but there are still a few stragglers. There's a bit of
preparatory work in ksm and unuse_pte(), but after that it's pretty
mechanical.
This patch (of 9):
Accept a folio as an argument and return a folio result. Removes a call
to compound_head() in do_swap_page(), and prevents folio & page from
getting out of sync in unuse_pte().
