  36 # DESCRIPTION:
  37 #       Reservations are enforced using the maximum of 'reserv' and 'refreserv'
  38 #
  39 # STRATEGY:
  40 #       1. Setting quota for parent filesystem.
  41 #       2. Setting reservation and refreservation for sub-filesystem.
  42 #       3. Verify the sub-fs reservation are enforced by the maximum of 'reserv'
  43 #          and 'refreserv'.
