From: Neeraj Upadhyay <neeraju@codeaurora.org>
The rcutorture_oom_notify() function has a misplaced close parenthesis that results in increasingly long delays in rcu_fwd_progress_check()'s checking for various RCU forward-progress problems. This commit therefore puts the parenthesis in the right place.
