From: Rom Lemarchand <[email protected]> Declare new ion_user_handle_t type to contain the token returned to user-space. This allows a 2-step migration of the user-space code to a new kernel header first, then will allow us to change the definition of the ion_user_handle_type_t to int without breaking the API.
