From 61dd3f246b3adaabff3241c586f2210ac91b05a4 Mon Sep 17 00:00:00 2001 From: Kinsey Ho Date: Wed, 27 Dec 2023 14:12:02 +0000 Subject: mm/mglru: add CONFIG_LRU_GEN_WALKS_MMU Add CONFIG_LRU_GEN_WALKS_MMU such that if disabled, the code that walks page tables to promote pages into the youngest generation will not be built. Also improves code readability by adding two helper functions get_mm_state() and get_next_mm().
