9512fe850e98fdd448c638ca63fdd92a8a510255ahl * ASSERTION:
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * Positive test for ring buffer policy.
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * SECTION: Buffers and Buffering/ring Policy;
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * Buffers and Buffering/Buffer Sizes;
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * Options and Tunables/bufsize;

9512fe850e98fdd448c638ca63fdd92a8a510255ahl * Options and Tunables/switchrate
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * We assume that a trace() of an integer stores at least 8 bytes. If ring
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * buffering is not working properly, this trace() will induce a drop, and the
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * counter won't be incremented. We set the switchrate to one second just to
9512fe850e98fdd448c638ca63fdd92a8a510255ahl * sure that a high switchrate doesn't mask broken ring buffers.
