+        depends on RING_BUFFER
+        help
+          This option creates a test to stress the ring buffer and bench mark it.
+          It creates its own ring buffer such that it will not interfer with
+          any other users of the ring buffer (such as ftrace). It then creates
+          a producer and consumer that will run for 10 seconds and sleep for
+          10 seconds. Each interval it will print out the number of events
+          it recorded and give a rough estimate of how long each iteration took.
+
+          It does not disable interrupts or raise its priority, so it may be
+          affected by processes that are running.
+
+          If unsure, say N
