The embedded member integrity_kobj member of struct gendisk violates the assumption of the driver core that only one struct kobject should be embedded into another object and then manages its lifetime. As the integrity_kobj is only used to hold a few sysfs attributes it can be replaced by direct device_attributes and removed.
