    [TIPC]: Overhaul of socket locking logic · 0c3141e9
    Allan Stephens authored
    This patch modifies TIPC's socket code to follow the same approach
    used by other protocols.  This change eliminates the need for a
    mutex in the TIPC-specific portion of the socket protocol data
    structure -- in its place, the standard Linux socket backlog queue
    and associated locking routines are utilized.  These changes fix
    a long-standing receive queue bug on SMP systems, and also enable
    individual read and write threads to utilize a socket without
    unnecessarily interfering with each other.
