21/*
22 * Header file used to associate behaviors with virtualized objects.
23 *
24 * A virtualized object is an internal, virtualized representation of
25 * OS entities such as persistent files, processes, or sockets. Examples
26 * of virtualized objects include vnodes, vprocs, and vsockets. Often
27 * a virtualized object is referred to simply as an "object."
28 *
29 * A behavior is essentially an implementation layer associated with
30 * an object. Multiple behaviors for an object are chained together,
31 * the order of chaining determining the order of invocation. Each
32 * behavior of a given object implements the same set of interfaces
33 * (e.g., the VOP interfaces).
34 *
35 * Behaviors may be dynamically inserted into an object's behavior chain,
36 * such that the addition is transparent to consumers that already have
37 * references to the object. Typically, a given behavior will be inserted
38 * at a particular location in the behavior chain. Insertion of new
39 * behaviors is synchronized with operations-in-progress (oip's) so that
40 * the oip's always see a consistent view of the chain.
41 *
42 * The term "interposition" is used to refer to the act of inserting
43 * a behavior such that it interposes on (i.e., is inserted in front
44 * of) a particular other behavior. A key example of this is when a
45 * system implementing distributed single system image wishes to
46 * interpose a distribution layer (providing distributed coherency)
47 * in front of an object that is otherwise only accessed locally.
48 *
49 * Note that the traditional vnode/inode combination is simply a virtualized
50 * object that has exactly one associated behavior.
51 *
52 * Behavior synchronization is logic which is necessary under certain
53 * circumstances that there is no conflict between ongoing operations
54 * traversing the behavior chain and those dynamically modifying the
55 * behavior chain. Because behavior synchronization adds extra overhead
56 * to virtual operation invocation, we want to restrict, as much as
57 * we can, the requirement for this extra code, to those situations
58 * in which it is truly necessary.
59 *
60 * Behavior synchronization is needed whenever there's at least one class
61 * of object in the system for which:
62 * 1) multiple behaviors for a given object are supported,
63 * -- AND --
64 * 2a) insertion of a new behavior can happen dynamically at any time during
65 * the life of an active object,
66 * -- AND --
67 * 3a) insertion of a new behavior needs to synchronize with existing
68 * ops-in-progress.
69 * -- OR --
70 * 3b) multiple different behaviors can be dynamically inserted at
71 * any time during the life of an active object
72 * -- OR --
73 * 3c) removal of a behavior can occur at any time during the life of
74 * an active object.
75 * -- OR --
76 * 2b) removal of a behavior can occur at any time during the life of an
77 * active object
