I'm not sure it's directly related to SRCU - it can change timings and freeing patterns enough to tickle other bugs. Since Alexey Dobriyan has reported it - are perhaps namespaces in use during this stress-test? Maybe it's some namespaces related bug that is more easily reproduced under SRCU - namespaces is not a commonly tested feature. Also, i've been running rcutorture stress-tests on a number of test-systems ever since this got reported (and they are running currently as well) and cannot see it - neither could Paul reproduce it. ( and Paul is very good in producing RCU related problems - he's triggered and fixed many RCU related problems that no-one else saw before. ) Ingo -- To unsubscribe from this list: send the line "unsubscribe kernel-testers" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
