The zone_reset_threshold option uses the 'sectors with data' accounting then it was described to have 'logical block' as its unit. However, the accounting was implemented with 'byte' unit. Fix the description of the option. Also, the zone_reset_threshold option works together with the zone_reset_frequency option. Describe this relation also.
