From 67311a36e5e1e56dfa7264c93db759b18217e114 Mon Sep 17 00:00:00 2001 From: Kemeng Shi Date: Mon, 17 Jul 2023 19:32:27 +0800 Subject: [PATCH] mm/page_ext: move page_ext_operations definition under CONFIG_PAGE_EXTENSION page_ext_operations should only be defined when CONFIG_PAGE_EXTENSION is enabled. Besides, this may detect missing reliance on CONFIG_PAGE_EXTENSION from future Page Extension clients at compile time.
