The new ioctl based infrastructure either commits or rollbacks all objects of the method as one transaction. In order to do that, we introduce a notion of dealing with a collection of objects that are related to a specific method. This also requires adding a notion of a method and attribute. A method contains a hash of attributes, where each bucket contains several attributes. The attributes are hashed according to their namespace which resides in the four upper bits of the id. For example, an object could be a CQ, which has an action of CREATE_CQ. This action has multiple attributes. For example, the CQ's new handle and the comp_channel. Each layer in this hierarchy - objects, methods and attributes is split into namespaces. The basic example for that is one namespace representing the default entities and another one representing the driver specific entities. When declaring these methods and attributes, we actually declare their specifications. When a method is executed, we actually allocates some space to hold auxiliary information. This auxiliary information contains meta-data about the required objects, such as pointers to their type information, pointers to the uobjects themselves (if exist), etc. The specification, along with the auxiliary information we allocated and filled is given to the finalize_objects function.
