This doesn't match the file name.

I think you have to have a virtual ~GamepadSharedBuffer() here, else
~GamepadSharedBufferImpl() mightn't get called.

+  virtual base::SharedMemory* shared_memory() = 0;
+  virtual blink::WebGamepads* buffer() = 0;
+
+  virtual void WriteBegin() = 0;
+  virtual void WriteEnd() = 0;
+};

+}  // namespace device
