That means\n there\u0027s a reference held on sdev_gendev until final disk put.\n Unfortunately, we use the driver model driver_remove to trigger\n del_gendisk (which removes the gendisk from visibility and decrements\n the refcount), so we\u0027ve introduced an unbreakable deadlock in the\n reference counting with this.\n\n I suggest simply reversing this patch at the moment.
