-        help
-          This option reduces the latency of the kernel by making certain
-          RCU sections preemptible. Normally RCU code is non-preemptible, if
-          this option is selected then read-only RCU sections become
-          preemptible. This helps latency, but may expose bugs due to
-          now-naive assumptions about each RCU read-side critical section
-          remaining on a given CPU through its execution.

-          This option provides tracing in RCU which presents stats
-          in debugfs for debugging RCU implementation.

-          Say Y here if you want to enable RCU tracing
