From d44ac1bebc47e46d62019808a893582f56496a98 Mon Sep 17 00:00:00 2001 From: Neeraj Upadhyay Date: Sat, 9 Mar 2019 00:40:45 +0530 Subject: [PATCH] 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.
