 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
