Subject: [PATCH] btrfs: make kobj_type structures constant
Date: Fri, 10 Feb 2023 02:13:40 +0000 [thread overview]
Message-ID: <20230210-kobj_type-btrfs-v1-1-16d3f33c17be@weissschuh.net> (raw)
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 definitions to prevent
modification at runtime.
