  35 # DESCRIPTION:
  36 #       Verify that the ZFS mdb dcmds and walkers are working as expected.
  37 #
  38 # STRATEGY:
  39 #       1) Given a list of dcmds and walkers
  40 #       2) Step through each element of the list
  41 #       3) Verify the output by checking for "mdb:" in the output string
  42 #
