[Mesa-dev] [PATCH 3/9] i965: Only wait for the fence bo to be signaled

[Chris Wilson]

The fence bo may be reused as an input fence to another batch, which
will cause us to treat it as busy until that subsequent batch is idle.
We only need to check if the fence has been signaled, which we can do by
checking the write status of the fence bo -- when the write is
completed, the fence is signaled.
