Indeed. So, as far as this series is concerned, it looks like either the
following solutions:
 - introduce a new scheduler, with a new name, and deprecate SEDF all 
   together
 - keep the name and the full existing interface, but warn the user when
   she touches one of the params that are no longer in use in the 
   implementation
would be ok.

Dario
