 // Specialization of the output surface that adapts it to implement the
 // content::SynchronousCompositor public API. This class effects an "inversion
 // of control" - enabling drawing to be  orchestrated by the embedding
 // layer, instead of driven by the compositor internals - hence it holds two
-// 'client' pointers (|client_| in the OutputSurface baseclass and
+// 'client' pointers (|client_| in the CompositorFrameSink baseclass and
 // |delegate_|) which represent the consumers of the two roles in plays.
 // This class can be created only on the main thread, but then becomes pinned
 // to a fixed thread when BindToClient is called.
