Subject: [PATCH] livepatch: Make kobj_type structures constant
Date: Fri, 17 Feb 2023 03:14:41 +0000 [thread overview]
Message-ID: <20230217-kobj_type-livepatch-v1-1-06ded292e897@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.
