From 5c09cfa5d21cfd820c183bd188be6f215d99770e Mon Sep 17 00:00:00 2001 From: Hongbo Li Date: Wed, 4 Sep 2024 09:19:51 +0800 Subject: [PATCH] cxl: Constify struct kobj_type This 'struct kobj_type' is not modified. It is only used in kobject_init_and_add() which takes a 'const struct kobj_type *ktype' parameter. Constifying this structure and moving it to a read-only section, and can increase over all security.
