If rcutorture is run on a quiet system with the rcutorture.stutter module parameter set high, then there can legitimately be an extended period during which no RCU forward progress takes place. This can result in false-positive no-forward-progress splats. This commit therefore makes rcu_torture_fwd_prog() create a self-propagating RCU callback to ensure that grace periods are in progress for the duration of the forward-progress test. Note that the RCU flavor under test must define ->call(), ->sync(), and ->cb_barrier() for this self-propagating callback to be created. If one or more of those rcu_torture_ops fields are NULL, then the rcu_torture_fwd_prog() function will silently proceed without creating the self-propagating callback. Signed-off-by: Paul E.
