    sys/fs/devfs         devfs_vnops.c 
    sys/fs/fifofs        fifo_vnops.c

    sys/vm               vnode_pager.c 
  Log:
  MFC: Always use an exclusive lock on the leaf vnode during an open() when
  shared lookups are enabled.  This closes a few races including a race where
  concurrent opens of a fifo could result in different v_fifoinfo structures
  in different threads.
