lockd.nlm_udpport=M [NFS] Assign UDP port.
Format: <integer>
+ 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.
