What do we need this for?

[mmenke, 2014/09/03 17:17:58]

We need it for DISALLOW_COPY_AND_ASSIGN.  You could use macros.h instead, which
is where it's actually defined, currently (It used to be in basictypes, IIRC,
but it moved, though basictypes still includes macros.h)

[Bence, 2014/09/03 18:30:14]

Changed to macros.h.

 #include "base/prefs/pref_member.h"
 
 class PrefService;
 
 namespace chrome_browser_net {
 class Predictor;
 }
 
 namespace prerender {
 class PrerenderManager;
 }
 
 namespace user_prefs {
 class PrefRegistrySyncable;
 }
 
 // Monitors network-related preferences for changes and applies them.
 // The supplied PrefService must outlive this NetPrefObserver.
 // Must be used only on the UI thread.
 class NetPrefObserver {
  public:
   // |prefs| must be non-NULL and |*prefs| must outlive this.
   // |prerender_manager| may be NULL. If not, |*prerender_manager| must
   // outlive this.
   NetPrefObserver(PrefService* prefs,
                   prerender::PrerenderManager* prerender_manager,

This isn't needed any more, and can get rid of the forward declaration, too. 
Same goes for the Predictor, I believe.

[Bence, 2014/09/03 17:05:17]

Done.

                   chrome_browser_net::Predictor* predictor);
   virtual ~NetPrefObserver();
 
   static void RegisterProfilePrefs(user_prefs::PrefRegistrySyncable* registry);

   BooleanPrefMember spdy_disabled_;
-  prerender::PrerenderManager* prerender_manager_;
   chrome_browser_net::Predictor* predictor_;

[mmenke, 2014/09/03 14:30:55]

Don't believe this is needed any more.

[Bence, 2014/09/03 17:05:17]

Done.
