+ Set time (s) between CPU-hotplug operations, or
+ zero to disable CPU-hotplug testing.
+
+ locktorture.shuffle_interval= [KNL]
+ Set task-shuffle interval (jiffies). Shuffling
+ tasks allows some CPUs to go into dyntick-idle
+ mode during the locktorture test.
+
+ locktorture.shutdown_secs= [KNL]

+ is useful for hands-off automated testing.
+
+ locktorture.stat_interval= [KNL]
+ Time (s) between statistics printk()s.
+
+ locktorture.stutter= [KNL]
+ Time (s) to stutter testing, for example,
+ specifying five seconds causes the test to run for
+ five seconds, wait for five seconds, and so on.
+ This tests the locking primitive's ability to
+ transition abruptly to and from idle.
+
+ locktorture.torture_runnable= [BOOT]
+ Start locktorture running at boot time.
+
+ locktorture.torture_type= [KNL]
+ Specify the locking implementation to test.

+ Set holdoff time (jiffies) between successive
+ callback-flood tests.
+
+ rcutorture.cbflood_intra_holdoff= [KNL]
+ Set holdoff time (jiffies) between successive
+ bursts of callbacks within a given callback-flood
+ test.
+
+ rcutorture.cbflood_n_burst= [KNL]
+ Set the number of bursts making up a given
+ callback-flood test. Set this to zero to
+ disable callback-flood testing.
+
+ rcutorture.cbflood_n_per_burst= [KNL]
+ Set the number of callbacks to be registered
+ in a given burst of a callback-flood test.
+
rcutorture.fqs_duration= [KNL]
Set duration of force_quiescent_state bursts.
Set time (s) between CPU-hotplug operations, or
zero to disable CPU-hotplug testing.

Start rcutorture running at boot time.
rcutorture.shuffle_interval= [KNL]
rcupdate.rcu_cpu_stall_timeout= [KNL]
Set timeout for RCU CPU stall warning messages.
+ rcupdate.rcu_task_stall_timeout= [KNL]
+ Set timeout in jiffies for RCU task stall warning
+ messages. Disable with a value less than or equal
+ to zero.
