-/*
- * Header file used to associate behaviors with virtualized objects.
- *
- * A virtualized object is an internal, virtualized representation of
- * OS entities such as persistent files, processes, or sockets.  Examples
- * of virtualized objects include vnodes, vprocs, and vsockets.  Often
- * a virtualized object is referred to simply as an "object."
- *
- * A behavior is essentially an implementation layer associated with
- * an object.  Multiple behaviors for an object are chained together,
- * the order of chaining determining the order of invocation.  Each
- * behavior of a given object implements the same set of interfaces
- * (e.g., the VOP interfaces).
- *
- * Behaviors may be dynamically inserted into an object's behavior chain,
- * such that the addition is transparent to consumers that already have
- * references to the object.  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
