>     dma-buf: Update reservation shared_count after adding the new fence
>     
>     We need to serialise the addition of a new fence into the shared list
>     such that the fence is visible before we claim it is there. Otherwise a
>     concurrent reader of the shared fence list will see an uninitialised
>     fence slot before it is set.
