Archived-At: List-Archive: List-Help: List-Post: List-Subscribe: List-Unsubscribe: Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Replace the open coded namespace active check with the one provided by libndctl - ndctl_namespace_is_active(). is_namespace_active() additionally checked for a non-NULL 'ndns', which the libndctl API doesn't do. However, all the callers either performed that check themselves, or made prior assumptions about ndns being valid by dereferencing it earlier.
