I don't think this is a good practice. It makes patch review or testing 
harder, the fact that a patch changes fate is useful information for 
reviewer. Not to mention that you can easily forgot to update the fate 
references before push, and a pushed commit which fails fate is a bad 
thing. So please, do not send patches which fails to pass fate.

Thanks,
