From ab8f11e5f6655861ad4758a7da76b2fc0e0dcc98 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Thu, 18 Aug 2011 09:30:32 -0700 Subject: rcu: Make rcu_torture_boost() exit loops at end of test One of the loops in rcu_torture_boost() fails to check kthread_should_stop(), and thus might be slowing or even stopping completion of rcutorture tests at rmmod time. This commit adds the kthread_should_stop() check to the offending loop. Signed-off-by: Paul E. McKenney Signed-off-by: Paul E.
