Typically, a given behavior will be inserted - * at a particular location in the behavior chain. Insertion of new - * behaviors is synchronized with operations-in-progress (oip's) so that - * the oip's always see a consistent view of the chain. - * - * The term "interposition" is used to refer to the act of inserting - * a behavior such that it interposes on (i.e., is inserted in front - * of) a particular other behavior. A key example of this is when a - * system implementing distributed single system image wishes to - * interpose a distribution layer (providing distributed coherency) - * in front of an object that is otherwise only accessed locally. - * - * Note that the traditional vnode/inode combination is simply a virtualized - * object that has exactly one associated behavior. - * - * Behavior synchronization is logic which is necessary under certain - * circumstances that there is no conflict between ongoing operations - * traversing the behavior chain and those dynamically modifying the - * behavior chain. Because behavior synchronization adds extra overhead - * to virtual operation invocation, we want to restrict, as much as - * we can, the requirement for this extra code, to those situations - * in which it is truly necessary. - * - * Behavior synchronization is needed whenever there's at least one class - * of object in the system for which: - * 1) multiple behaviors for a given object are supported, - * -- AND -- - * 2a) insertion of a new behavior can happen dynamically at any time during - * the life of an active object, - * -- AND -- - * 3a) insertion of a new behavior needs to synchronize with existing - * ops-in-progress. - * -- OR -- - * 3b) multiple different behaviors can be dynamically inserted at - * any time during the life of an active object - * -- OR -- - * 3c) removal of a behavior can occur at any time during the life of - * an active object. - * -- OR -- - * 2b) removal of a behavior can occur at any time during the life of an - * active object - * - */ - -/* - * Behavior head.
