39 Conventional zones are used for caching as well as for storing internal

43 placed in front of the zones from the zoned block device and will be handled
44 just like conventional zones.
46 The zones of the device(s) are separated into 2 types:
48 1) Metadata zones: these are conventional zones used to store metadata.
49 Metadata zones are not reported as usable capacity to the user.
