Say N, unless you absolutely know what you are doing.
+ tristate "Ring buffer benchmark stress tester"
+ depends on RING_BUFFER
+ 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
