-----------------------------------
[~hemanthboyina] Thank you very much for your comments.
1) I don't begin to do this work, we can use protobuf to do serialisation and
deserialisation
2) Indeed, we need to add our inodeTable.
3) Yeah, so careless i am.
Thank you twice for your carefully review, i have push a PR, look forward to
your review again.
