* 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
|
|
* listed will be rejected as input.
|
|
*
|
|
* 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
|
|
*
|
|
* Note: in the ZK_WILDCARDLIST case, the name serves as documentation
|
|
* for the expected name (bookmark, snapshot, property, etc) but there
|
|
* is no validation in the preflight zfs_check_input_nvpairs() check.
