> Procedure LOOKUP searches a directory for a specific name and returns the
> file handle for the corresponding file system object. NFS client sets
> filename as ".." to get the parent directory information.
> Currently ".." is considered invalid name component. We only allow ".." when
> the path is an inodeID path as "/.reserved/.inodes/.."
