[PATCH] rcu_torture_lock deadlock fix
rcu_torture_lock is used in a softirq-unsafe manner, but it is also
taken by rcu_torture_cb(), which may execute in softirq-context,
resulting in potential deadlocks.
The fix is to acquire rcu_torture_lock in a softirq-safe manner. With
this fix applied, the rcu-torture code passes validation.
