Hmm.

Do we really ever have a NULL 'nd' these days? Can you send me the
backtrace for whatever oops that was reported?

The reason I ask is because at least NFS also does just

        if (nd->flags & LOOKUP_RCU)
                return -ECHILD;

in its nfs_lookup/open_revalidate() functions. As does cifs, ncpfs, p9
and coda from a quick grep.
