  	default n
  	help
  	  This option provides a kernel module that runs performance
  	  tests on the RCU infrastructure.  The kernel module may be built
  	  after the fact on the running kernel to be tested, if desired.
  
  	  Say Y here if you want RCU performance tests to be built into
  	  the kernel.
  	  Say M if you want the RCU performance tests to build as a module.
  	  Say N if you are unsure.
  
  config RCU_TORTURE_TEST
  	tristate "torture tests for RCU"
  	depends on DEBUG_KERNEL
  	select TORTURE_TEST

  	help
  	  This option provides a kernel module that runs torture tests
  	  on the RCU infrastructure.  The kernel module may be built
  	  after the fact on the running kernel to be tested, if desired.
  
  	  Say Y here if you want RCU torture tests to be built into
  	  the kernel.
  	  Say M if you want the RCU torture tests to build as a module.

  	int "RCU CPU stall timeout in seconds"
  	depends on RCU_STALL_COMMON
  	range 3 300
  	default 21
  	help
  	  If a given RCU grace period extends more than the specified
  	  number of seconds, a CPU stall warning is printed.  If the
  	  RCU grace period persists, additional CPU stall warnings are
  	  printed at more widely spaced intervals.
  
  config RCU_TRACE
  	bool "Enable tracing for RCU"
  	depends on DEBUG_KERNEL
  	default y if TREE_RCU
  	select TRACE_CLOCK
  	help
  	  This option enables additional tracepoints for ftrace-style
  	  event tracing.
  
  	  Say Y here if you want to enable RCU tracing
  	  Say N if you are unsure.
  
  config RCU_EQS_DEBUG
  	bool "Provide debugging asserts for adding NO_HZ support to an arch"
  	depends on DEBUG_KERNEL
  	help
  	  This option provides consistency checks in RCU's handling of
  	  NO_HZ.  These checks have proven quite helpful in detecting
  	  bugs in arch-specific NO_HZ code.
  
  	  Say N here if you need ultimate kernel/user switch latencies
  	  Say Y if you are unsure
