    rcutorture: Check GP completion at stutter end · 474e59b4
    Paul E. McKenney authored
    The rcu_torture_writer() function invokes stutter_wait() at the end of
    each writer pass, which occasionally blocks for an extended time period
    in order to ensure that RCU can handle intermittent loads.  But part of
    handling a busy period is invoking all the callbacks before the end of
    the idle period induced by stutter_wait().
    
    This commit therefore adds a return value to stutter_wait() indicating
    whether stutter_wait() actually waited.  In addition, this commit causes
    rcu_torture_writer() to test this value and if set, checks that all the
    elements of the rcu_tortures[] array have been freed up.
