  Modified files:
    sys/ufs/ufs          ufs_vnops.c 
  Log:
  Change UFS from using vop_stdlock to using its own ufs_lock.
  In ufs_lock, check for attempts to acquire shared locks on
  snapshot files and change them to be exclusive locks. This
  change eliminates deadlocks and machine lockups reported in
  -current since most read requests started using shared lock
  requests.
