--- Comment #2 from Alan Somers <asomers@FreeBSD.org> ---
I don't think that changing the signature of VOP_READDIR is necessary to fix
the NFS server.  On architectures where u_long is 32-bits, the NFS server will
simply 0-extend it to 64-bits before placing it on the wire.

OTOH, ever since the ino64 project added a d_off field to struct dirent, I
think the cookies array is redundant.  We could remove it entirely from
VOP_READDIR, and just populate the NFS cookie from d_off.  That's 64-bits on
all architectures.
