Perhaps it would make sense to update the core code to release using kfree_const(), allowing drivers to set the initial value with kstrdup_const(). Drivers that currently use kstrdup() or kasprintf() will continue to work [but if they kstrdup() a string literal they could be changed to use kstrdup_const]. Rasmus
