Command line utility to use zonefs file system

 Zonefs is a very simple file system exposing each zone of a
 zoned block device as a file. zonefs does not have complex
 on-disk metadata. Its implementation relies solely on a super
 block stored at LBA 0 of the device. On mount, zonefs uses
 zone configuration information obtained directly from the
 device to populate the mount point with files representing
 the device zones.
