Hi!
> +The above commands create a NOVA instance on `/dev/pmem0` and mounts it on
> +`/mnt/nova`.
> +
> +NOVA support several module command line options:
> +
> + * measure_timing: Measure the timing of file system operations for profiling (default: 0)
> +
> + * inplace_data_updates: Update data in place rather than with COW (default: 0)
> +
> +To recover an existing NOVA instance, mount NOVA without the init option, for example:
> +
> +# mount -t NOVA /dev/pmem0 /mnt/nova
