Thomas i got one last question to finish cleaning up my fence code :)
The wait callback is there to wait for a fence and mask argument is
the type we are waiting for this fence ? I don't understand why we
need the mask argument while the fence already have its type defined ?
Is this for the following case:

Userspace submit cmd with a fence toto of type FENCE_TYPE_EXE
Userspace say well now i want to wait for toto fence but with
	  type RW flush and not only FENCE_TYPE_EXE.
