It is identical to the no_formal_ino in all recent kernels and we use that value for NFS generation number purposes. Really we should be using this value and not the no_formal_ino one, but the switch didn't get made when the original change was made. Both values are identical, except for very old versions of the code. I think we should retain this field though, since it can be useful for debugging, Steve.
