Its filename was mm-page_owner-hoist-config_memcg-to-function-level-for-print_page_owner_memcg.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: Ye Liu Subject: mm/page_owner: hoist CONFIG_MEMCG to function level for print_page_owner_memcg() Date: Wed, 1 Jul 2026 14:10:47 +0800 The print_page_owner_memcg() function has CONFIG_MEMCG guarding its entire body via #ifdef inside the function, which leaves a no-op { return ret; } when the config is disabled. Hoist the #ifdef to the top level so the real implementation and the empty stub are two clearly separated definitions. No functional change.
