The classid of a process is changed either when a process is moved to or from a cgroup or when the net_cls.classid file is updated. Previously net_cls only supported propogating these changes to the cgroup's related sockets when a process was added or removed from the cgroup. This means it was neccessary to remove and re-add all processes to a cgroup in order to update its classid. This change introduces support for doing this dynamically - i.e. when the value is changed in the net_cls_classid file, this will also trigger an update to the classid associated with all sockets controlled by the cgroup. This mimics the behaviour of other cgroup subsystems. net_prio circumvents this issue by storing an index into a table with each socket (and so any updates to the table, don't require updating the value associated with the socket). net_cls, however, passes the socket the classid directly, and so this additional step is needed.
