  35 # DESCRIPTION:
  36 #       Quotas are enforced using the minimum of the two properties:
  37 #       quota & refquota
  38 #
  39 # STRATEGY:
  40 #       1. Set value for quota and refquota. Quota less than refquota.
  41 #       2. Creating file which should be limited by quota.
  42 #       3. Switch the value of quota and refquota.
  43 #       4. Verify file should be limited by refquota.
