From: Neeraj Upadhyay Date: Fri, 8 Mar 2019 19:10:45 +0000 (+0530) Subject: rcutorture: Fix expected forward progress duration in OOM notifier X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d44ac1bebc47e46d62019808a893582f56496a98;p=linux.git rcutorture: Fix expected forward progress duration in OOM notifier 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. Signed-off-by: Neeraj Upadhyay Signed-off-by: Paul E.
