> 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/.."
