Please make this method asynchronous, it should be something like:
typedef base::Callback<void(DBusMethodCallStatus call_status, bool is_mounted,
bool is_ephemeral> IsMountedForUserCallback;
virtual void IsMountedForUser(const std::string& username, const
IsMountedForUserCallback& callback) = 0;

I know synchronous API is easier to use, but we are making all D-Bus method
calls asynchronous to reduce UI jank. (crbug.com/127186)
