    kernel - Refactor inum stat data for sockets
    
    * Assign a dummy inode number to all sockets.  We previously were
      only assigning a dummy inode number to unix domain sockets.  Use
      the new pcpu facility and store the inum in the socket structure.
    
    * Rip out the old inode number assigner for unix domain sockets, it
      was using an atomic_fetchadd_long() on a global variable, introducing
      unnecessary SMP stalls.  And it was specific to unix domain sockets.
      The new facility is generic to all sockets and uses a pcpu data
      structure.
