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.
