From e3089fd0b0199a368db4039122b241139cc665f3 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Tue, 26 Mar 2024 17:10:26 +0000 Subject: mm: make folio_test_idle and folio_test_young take a const argument If these functions are defined in page-flags.h, they already take a const argument; make it true for these alternate definitions too.
