The feature adds support for associating data to a zone that is in the Empty state. Upon successful completion, the specified zone transitions to the Closed state and further writes can be issued to the zone. The data is lost when the zone at some point transitions to the Empty state, the Read Only state, or the Offline state. For example, the lifetime of the data is valid until a zone reset is issued on the specific zone. The first patch adds support for the zone_desc_ext_bytes queue sysfs entry, and the second patch adds a ioctl to allow user-space to associate data to a specific zone. Support for the feature can be detected through the zone_desc_ext_bytes queue sysfs. A value larger than zero indicates support, and zero value indicates no support.
