+# DESCRIPTION:
+# A zfs file system quota limits the amount of pool space
+# available to a given ZFS file system. Once exceeded, it is impossible
+# to write any more files to the file system.
+#
+# STRATEGY:
+# 1) Apply quota to the ZFS file system
+# 2) Exceed the quota
+# 3) Attempt to write another file
+# 4) Verify the attempt fails with error code EDQUOTA (linux 122, others 49)
+#
+#

+# cleanup to be used internally as otherwise quota assertions cannot be
+# run independently or out of order
