From 02cd4eb81c14ee64b062383c7e25fd8599b18f3d Mon Sep 17 00:00:00 2001 From: =?utf8?q?Thomas=20Wei=C3=9Fschuh?= Date: Fri, 24 Mar 2023 15:35:27 +0000 Subject: [PATCH] mm/damon/sysfs: make more kobj_type structures constant MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Since commit ee6d3dd4ed48 ("driver core: make kobj_type constant.") the driver core allows the usage of const struct kobj_type. Take advantage of this to constify the structure definition to prevent modification at runtime. These structures were not constified in commit e56397e8c40d ("mm/damon/sysfs: make kobj_type structures constant") as they didn't exist when that patch was written.
