[PATCH v2 3/3] mm/swap: Convert deactivate_page() to folio_deactivate()

From: Vishal Moola (Oracle)
Date: Wed Dec 07 2022 - 18:02:21 EST


Deactivate_page() has already been converted to use folios, this change
converts it to take in a folio argument instead of calling page_folio().
It also renames the function folio_deactivate() to be more consistent
with other folio functions.
