Modifying the filesystem code

[Rajat Sharma]

Dinesh,

I think it would be better if you can describe our aim of the task in
plain English without any technical details. May be people can suggest
you an altogether better approach, because its getting hard to know
what exactly you want to do, is it mkdir or create or both you are
interested in? If every creation has to be prefixed, may be you don't
have to even change any of inode operations.

In short, just come up with our aim statement in plain English.
