The option is named and discribed as "no_zone_write_lock", which is a block
layer concept. Given that this sets driver_preserves_write_order and does not
touch the use_zone_write_locking limit, I think it is better to name the option
"preserve_write_order" (or similar) to avoid confusion.
I will make this change.
Thanks,
