I have removed these changes from the CL.

 #include "content/child/process_control_impl.h"
 
 namespace content {
 
 // Customization of ProcessControlImpl for the GPU process.
 class GpuProcessControlImpl : public ProcessControlImpl {
  public:
-  GpuProcessControlImpl();
+  GpuProcessControlImpl(
+      scoped_refptr<base::SingleThreadTaskRunner> gpu_task_runner);

gpu_main_task_runner just to be more explicit?

   ~GpuProcessControlImpl() override;
 
   // ProcessControlImpl:
   void RegisterApplicationFactories(ApplicationFactoryMap* factories) override;
 
  private:
+  scoped_refptr<base::SingleThreadTaskRunner> gpu_task_runner_;
+
   DISALLOW_COPY_AND_ASSIGN(GpuProcessControlImpl);
 };
 
 }  // namespace content
 
 #endif  // CONTENT_GPU_GPU_PROCESS_CONTROL_IMPL_H_
