+# DESCRIPTION:
+#	Verify automatic trim pool data integrity.
+#
+# STRATEGY:
+#	1. Create a pool on sparse file vdevs to trim.
+#	2. Set autotrim=on to enable asynchronous pool trimming.
+#	3. Generate some interesting pool data which can be trimmed.
+#	4. Verify trim IOs of the expected type were issued for the pool.
+#	5. Verify data integrity of the pool after trim.
+#	6. Repeat test for striped, mirrored, and RAIDZ pools.
