  1. Cannot configure nand erase delay
  2. The entire ZNS has only one shared read-write wwp
  3. The next_fc_avail_time of fc will be modified repeatedly under multi-threading, resulting in incorrect simulation results
  4. The fixed zone_size (NVME_DEFAULT_ZONE_SIZE) may be inconsistent with the zns_num_ch and zns_num_lun configured by itself.
  5. lpn = lba / 8, not 4096
