+# CONFIG_RCU_REF_SCALE_TEST:
+# 
+# This option provides a kernel module that runs performance tests
+# useful comparing RCU with various read-side synchronization mechanisms.
+# The kernel module may be built after the fact on the running kernel to be
+# tested, if desired.
+# 
+# Say Y here if you want these performance tests built into the kernel.
+# Say M if you want to build it as a module instead.
+# Say N if you are unsure.
+# 
+# Symbol: RCU_REF_SCALE_TEST [=n]
+# Type  : tristate
+# Defined at kernel/rcu/Kconfig.debug:64
+#   Prompt: Scalability tests for read-side synchronization (RCU and others)
+#   Depends on: DEBUG_KERNEL [=y]
+#   Location:
+#     -> Kernel hacking
+#       -> RCU Debugging
+# Selects: TORTURE_TEST [=m] && SRCU [=y] && TASKS_RCU [=y] && TASKS_RUDE_RCU [=y] && TASKS_TRACE_RCU [=y]
