> During mkdir - the directory create request handler in the OM, create separate key table entries for each of the directories in the path.
> This will ensure that every directory that exists in the FS namespace is explicitly listed as an entry in the key table -  instead of being implicit as part of the key of the leaf level directory or file.
> This subsequently makes file create operation efficient - there is no requirement to run an expensive iterator on the key table to determine if the file name already exists as a directory.
