+# DESCRIPTION:
+#	Concurrent sync writes with log offline/online works.
+#
+# STRATEGY:
+#	1. Configure "zfs_commit_timeout_pct"
+#	2. Create pool with a log device.
+#	3. Concurrently do the following:
+#	   3.1. Perform 8K sync writes
+#	   3.2. Perform log offline/online commands
+#	4. Loop to test with growing "zfs_commit_timeout_pct" values.
