  * 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

  *    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.

  *   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

  *   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

  *     - The tipc_port spin_lock. This is protecting each port instance
