From: Matias Bjørling <matias.bjorling@xxxxxxx> In the zoned storage model, the sectors within a zone are typically all writeable. With the introduction of the Zoned Namespace (ZNS) Command Set in the NVM Express organization, the model was extended to have a specific writeable capacity. Extend the zone descriptor data structure with a zone capacity field to indicate to the user how many sectors in a zone are writeable. Introduce backward compatibility in the zone report ioctl by extending the zone report header data structure with a flags field to indicate if the capacity field is available.
