From f2d273927ea49e2f85b660aeca26f58b8a15d385 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Tue, 27 Apr 2021 10:37:50 -0400 Subject: mm/swap: Add folio_activate() This replaces activate_page() and eliminates lots of calls to compound_head(). Saves net 118 bytes of kernel text. There are still some redundant calls to page_folio() here which will be removed when pagevec_lru_move_fn() is converted to use folios.
