If an rcu_torture_boost() kthread determines that its grace period has not yet ended, it invokes rcu_torture_boost_failed() which checks whether enough time has elapsed for this to be considered a failure of RCU priority boosting, and, if so, flags the error. Unfortunately, that kthread might be preempted for some seconds between the time that it checks the grace period and the time that it checks the time. This delay can result in a false positive, featuring a complaint that a particular grace period has not ended, followed by a diagnostic dump featuring a much later grace period. This commit avoids these false positives by rechecking for the end of the grace period after the time check. Signed-off-by: Paul E. McKenney <paulmck@kernel.org> |
