Subject: [PATCH] mm: slub: make kobj_type structure constant
Date: Mon, 20 Feb 2023 23:25:28 +0000	[thread overview]
Message-ID: <20230220-kobj_type-mm-slub-v1-1-5ae49b96d9aa@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 definition to prevent
modification at runtime.
