 This module has the following parameters:
 
+fqs_duration    Duration (in microseconds) of artificially induced bursts
+                of force_quiescent_state() invocations.  In RCU
+                implementations having force_quiescent_state(), these
+                bursts help force races between forcing a given grace
+                period and that grace period ending on its own.
+
+fqs_holdoff     Holdoff time (in microseconds) between consecutive calls
+                to force_quiescent_state() within a burst.
+
+fqs_stutter     Wait time (in seconds) between consecutive bursts
+                of calls to force_quiescent_state().

 irqreaders      Says to invoke RCU readers from irq level.  This is currently
                 done via timers.  Defaults to "1" for variants of RCU that
                 permit this.  (Or, more accurately, variants of RCU that do

-As before, the first four lines are similar to those for RCU.
-The last line shows the task-migration state.  The first number is
--1 if synchronize_sched_expedited() is idle, -2 if in the process of
-posting wakeups to the migration kthreads, and N when waiting on CPU N.
-Each of the colon-separated fields following the "/" is a CPU:state pair.
-Valid states are "0" for idle, "1" for waiting for quiescent state,
-"2" for passed through quiescent state, and "3" when a race with a
-CPU-hotplug event forces use of the synchronize_sched() primitive.
