* The TIPC locking policy is designed to ensure a very fine locking
* granularity, permitting complete parallel access to individual
* port and node/link instances. The code consists of three major
* port and node/link instances. The code consists of three major
* locking domains, each protected with their own disjunct set of locks.
*
* 1: The routing hierarchy.
* Comprises the structures 'zone', 'cluster', 'node', 'link'
* and 'bearer'. The whole hierarchy is protected by a big
* read/write lock, tipc_net_lock, to enssure that nothing is added
* or removed while code is accessing any of these structures.

* or removed while code is accessing any of these structures.
* This layer must not be called from the two others while they
* hold any of their own locks.
* Neither must it itself do any upcalls to the other two before
* it has released tipc_net_lock and other protective locks.
*
* Within the tipc_net_lock domain there are two sub-domains;'node' and
* Within the tipc_net_lock domain there are two sub-domains;'node' and
* 'bearer', where local write operations are permitted,
* provided that those are protected by individual spin_locks
* per instance. Code holding tipc_net_lock(read) and a node spin_lock
* per instance. Code holding tipc_net_lock(read) and a node spin_lock
* is permitted to poke around in both the node itself and its
* subordinate links. I.e, it can update link counters and queues,
* change link state, send protocol messages, and alter the
* "active_links" array in the node; but it can _not_ remove a link
* subordinate links. I.e, it can update link counters and queues,
* change link state, send protocol messages, and alter the
* "active_links" array in the node; but it can _not_ remove a link
* or a node from the overall structure.
* Correspondingly, individual bearers may change status within a
* tipc_net_lock(read), protected by an individual spin_lock ber bearer
* Correspondingly, individual bearers may change status within a
* tipc_net_lock(read), protected by an individual spin_lock ber bearer
* instance, but it needs tipc_net_lock(write) to remove/add any bearers.
*
*
* 2: The transport level of the protocol.
* This consists of the structures port, (and its user level
* representations, such as user_port and tipc_sock), reference and
* tipc_user (port.c, reg.c, socket.c).

* This consists of the structures port, (and its user level
* representations, such as user_port and tipc_sock), reference and
* tipc_user (port.c, reg.c, socket.c).
*
* This layer has four different locks:
* - The tipc_port spin_lock. This is protecting each port instance
* from parallel data access and removal. Since we can not place
* this lock in the port itself, it has been placed in the
* from parallel data access and removal. Since we can not place
* this lock in the port itself, it has been placed in the
* corresponding reference table entry, which has the same life
* cycle as the module. This entry is difficult to access from
* outside the TIPC core, however, so a pointer to the lock has
* been added in the port instance, -to be used for unlocking
* cycle as the module. This entry is difficult to access from
* outside the TIPC core, however, so a pointer to the lock has
* been added in the port instance, -to be used for unlocking

* - A read/write lock to protect the reference table itself (teg.c).

* - A read/write lock to protect the reference table itself (teg.c).
* (Nobody is using read-only access to this, so it can just as
* well be changed to a spin_lock)
* - A spin lock to protect the registry of kernel/driver users (reg.c)
* - A global spin_lock (tipc_port_lock), which only task is to ensure
* - A global spin_lock (tipc_port_lock), which only task is to ensure
* consistency where more than one port is involved in an operation,
* i.e., whe a port is part of a linked list of ports.
* There are two such lists; 'port_list', which is used for management,
* and 'wait_list', which is used to queue ports during congestion.
*
*
* 3: The name table (name_table.c, name_distr.c, subscription.c)
* - There is one big read/write-lock (tipc_nametbl_lock) protecting the
* overall name table structure. Nothing must be added/removed to
* - There is one big read/write-lock (tipc_nametbl_lock) protecting the
