commit e459a947395e9aba50eba6cbf8f13ee803856314

    ctdb: when we fill the client packet queue we need to drop the client
    
    We can't just drop packets to the list, as those packets could be part
    of the core protocol the client is using. This happens (for example)
    when Samba is doing a traverse. If we drop a traverse packet then
    Samba hangs indefinately. We are better off dropping the ctdb socket
    to Samba.

    ctdb: move ctdb_io.c to use TLIST_*() macros
    
    This will make large packet queues much more efficient

commit 46cd20ebe9b0933ba663dad342661a7dc0a3926f
Author: Andrew Tridgell <tridge at samba.org>
Date:   Thu Feb 4 14:13:49 2010 +1100

    util: added TLIST_*() macros
    
    The TLIST_*() macros are like the DLIST_*() macros, but take both a
    head and tail pointer for the list. This means that adding an element
    to the end of the list is efficient (it doesn't need to walk the
    list).
    
    We should move all uses of the DLIST_*() macros which use
    DLIST_ADD_END() to use the TLIST_*() macros instead.
