Could you perhaps share it? (Maybe that test case could even be added tot the commit message. I seem to remember an earlier commit that you were involved with which had a test case added. That helped me understand eventpoll's interface - at least enough to pinpoint the problem. Looking at a test case is much easier than grepping through a program like systemd. Issues in non-test case programs tend to increase the bug hunting challenge: one is faced with an issue in an interface one hasn't used before triggered by a program one hasn't studied before.) > Paul, are you able to test systemd against this? I hope to do so shortly (ie, in the next 24 hours).
