From: Thomas Weißschuh Date: Thu, 9 Feb 2023 03:18:35 +0000 (+0000) Subject: ext4: make kobj_type structures constant X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=60db00e0a1490adcdc8b80887f7caf954d8bcd3e;p=linux.git ext4: make kobj_type structures constant 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.
