Call blk_queue_chunk_sectors() and blk_queue_max_zone_append_sectors() to respectively set a ZBC device zone size and maximum zone append sector limit before executing blk_revalidate_disk_zones() to allow this function to check zone limits. Since blk_queue_max_zone_append_sectors() already caps the device maximum zone append limit to the zone size and to the maximum command size, the max_append value passed to blk_queue_max_zone_append_sectors() is simplified to the maximum number of segments times the number of sectors per page.
