At least I cannot see why the AFS patch differs from the NFS one in
those two details.

Actually, what the patch itself changes doesn't differ significantly - the
difference is in the patch context.

Well, AFS_FS is itself marked as being experimental, so I'm not sure that the
AFS_FSCACHE option needs to be also.

Good point.  The other typo should be fairly obvious, though.
