What has to be submitted in this patch? Is it about some partial implementation from our project proposal or about contribution apart from our proposal? In the latter case, if we have already contributed then we do not have to worry about it?

It's the latter case and you don't have to worry about this if you have contributed at least one patch. Well, if I were a student, I would worry a little if my patch had not been accepted...
