This commit adds a kthread that loops going into and out of RCU read-side critical sections, but also including a cond_resched(), optionally guarded by a check of need_resched(), in that same loop. This commit relies solely on rcu_torture_writer() progress to judge the forward progress of grace periods. Note that Tasks RCU and SRCU are exempted from forward-progress testing due their (intentionally) less-robust forward-progress guarantees. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
