From 78c85147b72d7626e312c0115b0f407de1fdf83a Mon Sep 17 00:00:00 2001 From: SeongJae Park Date: Tue, 24 Aug 2021 09:59:46 +1000 Subject: [PATCH] mm/damon/Kconfig: Hide PAGE_IDLE_FLAG from users Commit 2a058a1a9914 ("mm/idle_page_tracking: make PG_idle reusable") of linux-mm[1] makes CONFIG_PAGE_IDLE_FLAG option to be presented to the user. However, the option is hard to be understood by users. Also, it is not intended to be set by users but other kernel subsystems like DAMON or IDLE_PAGE_TRACKING. To avoid confusions, this commit removes the prompt so that the option is not presented to the user.
