It is not a bug fix. It was not needed before because klp_register_patch() did not checked this field when failed. But this patch started to use the generic klp_free_patch_start()/klp_free_patch_finish() in both klp_unregister_patch() and in klp_init_patch() error patch. Therefore we need to have a valid value from the beginning. Best Regards, Petr
