A target driver support zoned block devices and exposing it as such may receive REQ_OP_ZONE_REPORT request for the user to determine the mapped device zone configuration. To process properly such request, the target driver may need to remap the zone descriptors provided in the report reply. The helper function dm_remap_zone_report() does this generically using only the target start offset and length and the start offset within the target device.
dm_remap_zone_report() will remap the start sector of all zones reported. If the report includes sequential zones, the write pointer position of these zones will also be remapped.
