From: "Paul E. McKenney" <[email protected]> Because rcutorture runs CPU-bound in the kernel, it can prevent grace periods from being reported. In RCU_COND_RESCHED_QS=y builds, the cond_resched() calls handle this reporting. This commit therefore forces RCU_COND_RESCHED_QS=y for the TREE01 rcutorture configuration, which is otherwise prone to spurious RCU CPU stall warnings.
