- * However we cannot deregister the callback on the removal
- * of the last nft flow as this runs into a deadlock situation.
- * So deregister the callback on removal of the last pre_ct flow
- * and remove any remaining nft flow entries. We also cannot
- * save this state and delete the callback later since the
