That is not possible, the first few bytes of the structure must match
struct fid from fstypes.h.

The structure is only used to construct opaque tokens for filehandles,
and the encoding includes the size, so I see no problem.

Indeed rebooting with an updated kernel will give active NFS clients
problems, but I am not sure we should realy care nor how we could
possibly avoid this one time issue. We have changed encoding of
filehandles before (at least once).
