nit: more conventional to use NOTREACHED here so you don't have to repeat the
conditional:

  if (!handle) {
    NOTREACHED();
    return;
  }

Done.

+  if (!handle)
+    return;
+  WebSocketStreamHandleImpl* impl =
+      static_cast<WebSocketStreamHandleImpl*>(handle);
+  impl->SetUserData(handle, new SocketStreamHandleData(render_view_id));
+}
+
+// static
+const SocketStreamHandleData* SocketStreamHandleData::ForHandle(
+    WebSocketStreamHandle* handle) {
+  if (!handle)
+    return NULL;
+  WebSocketStreamHandleImpl* impl =
+      static_cast<WebSocketStreamHandleImpl*>(handle);
+  return static_cast<SocketStreamHandleData*>(impl->GetUserData(handle));
+}
