    torture: Allow inter-stutter interval to be specified · ff3bf92d
    Paul E. McKenney authored
    Currently, the inter-stutter interval is the same as the stutter duration,
    that is, whatever number of jiffies is passed into torture_stutter_init().
    This has worked well for quite some time, but the addition of
    forward-progress testing to rcutorture can delay processes for several
    seconds, which can triple the time that they are stuttered.
    
    This commit therefore adds a second argument to torture_stutter_init()
    that specifies the inter-stutter interval.  While locktorture preserves
    the current behavior, rcutorture uses the RCU CPU stall warning interval
    to provide a wider inter-stutter interval.
