23 Using zloop, zoned block devices with a configurable capacity, zone size and
24 number of conventional zones can be created. The storage for each zone of the
25 device is implemented using a regular file with a maximum size equal to the zone
26 size. The size of a file backing a conventional zone is always equal to the zone
27 size. The size of a file backing a sequential zone indicates the amount of data
29 indicates the position of the write pointer of the zone.
31 When resetting a sequential zone, its backing file size is truncated to zero.
32 Conversely, for a zone finish operation, the backing file is truncated to the
33 zone capacity. With this, a zloop zoned block device can be configured with a
