Paul E. McKenney 1909121a61 rcutorture: Fix cleanup path for invalid torture_type strings ... [ Upstream commit b813afae7ab6a5e91b4e16cc567331d9c2ae1f04 ] If the specified rcutorture.torture_type is not in the rcu_torture_init() function's torture_ops[] array, rcutorture prints some console messages and then invokes rcu_torture_cleanup() to set state so that a future torture test can run. However, rcu_torture_cleanup() also attempts to end the test that didn't actually start, and in doing so relies on the value of cur_ops, a value that is not particularly relevant in this case. This can result in confusing output or even follow-on failures due to attempts to use facilities that have not been properly initialized. This commit therefore sets the value of cur_ops to NULL in this case and inserts a check near the beginning of rcu_torture_cleanup(), thus avoiding relying on an irrelevant cur_ops value.
