-   amount of credit `credit' and the most credit you can ever have
-   `credit_cap'.  The `peak rate' becomes the cost of passing the
-   test, `cost'.
-
-   `prev' tracks the last packet hit: you gain one credit per jiffy.
-   If you get credit balance more than this, the extra credit is
-   discarded.  Every time the match passes, you lose `cost' credits;
-   if you don't have that many, the test fails.
-
-   See Alexey's formal explanation in net/sched/sch_tbf.c.
-
-   To avoid underflow, we multiply by 128 (ie. you get 128 credits per
-   jiffy).  Hence a cost of 2^32-1, means one pass per 32768 seconds
-   at 1024HZ (or one every 9 hours).  A cost of 1 means 12800 passes

+ * routines of the form "dbg_link_XXX()" have been created that will capture
+ * debug info into a link's personal print buffer, which can then be dumped
+ * into the TIPC system log (LOG) upon request.
+ *
+ * To enable per-link debugging, use LINK_LOG_BUF_SIZE to specify the size
+ * of the print buffer used by each link.  If LINK_LOG_BUF_SIZE is set to 0,
+ * the dbg_link_XXX() routines simply send their output to the standard 
+ * debug print buffer (DBG_OUTPUT), if it has been defined; this can be useful
+ * when there is only a single link in the system being debugged.
+ *
+ * Notes:
+ * - When enabled, LINK_LOG_BUF_SIZE should be set to at least 1000 (bytes)
+ * - "l_ptr" must be valid when using dbg_link_XXX() macros

+/* 
+ * 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 
+ * 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, net_lock, to enssure that nothing is added 
+ *    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 net_lock and other protective locks.
+ *
+ *   Within the 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 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 
+ *   or a node from the overall structure.
+ *   Correspondingly, individual bearers may change status within a 
+ *   net_lock(read), protected by an individual spin_lock ber bearer 
+ *   instance, but it needs 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 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 
+ *       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 
+ *       only.
+ *     - 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 (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 (nametbl_lock) protecting the 
+ *       overall name table structure. Nothing must be added/removed to 
+ *       this structure without holding write access to it.
+ *     - There is one local spin_lock per sub_sequence, which can be seen
+ *       as a sub-domain to the nametbl_lock domain. It is used only
+ *       for translation operations, and is needed because a translation
+ *       steps the root of the 'publication' linked list between each lookup.
+ *       This is always used within the scope of a nametbl_lock(read).
+ *     - A local spin_lock protecting the queue of subscriber events.
