+        locktorture.nreaders_stress= [KNL]
+                        Set the number of locking read-acquisition kthreads.
+                        Defaults to being automatically set based on the
+                        number of online CPUs.

+        locktorture.nwriters_stress= [KNL]
+                        Set the number of locking write-acquisition kthreads.
+
+        locktorture.onoff_holdoff= [KNL]
+                        Set time (s) after boot for CPU-hotplug testing.
+
+        locktorture.onoff_interval= [KNL]
+                        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]
+                        Set time (s) after boot system shutdown.  This
+                        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.
+
+        locktorture.verbose= [KNL]
+                        Enable additional printk() statements.
