| * IOC Keys are used to document and validate user->kernel interface inputs. |
| * See zfs_keys_recv_new for an example declaration. Any key name that is not |

| * The keyname 'optional' is always allowed, and must be an nvlist if present. |
| * Arguments which older kernels can safely ignore can be placed under the |
| * "optional" key. |
| * |
| * When adding new keys to an existing ioc for new functionality, consider: |
| * - adding an entry into zfs_sysfs.c zfs_features[] list |
| * - updating the libzfs_input_check.c test utility |

| * is no validation in the preflight zfs_check_input_nvpairs() check. |
