  Modified files:
    sys/ufs/ffs          ffs_alloc.c 
  Log:
  Fix a DIV0 in case a large value for fs_avgfilesize or fs_avgfpdir
  is given (with newfs or tunefs) and dirsize overflows.
  
  In case dirsize is <= 0 because of an overflow set maxcontigdirs
  to 0 so it will be 1 later. This is what would happen for large
  fs_avgfilesize. [1]
