From: Eric Dumazet <edumazet@google.com> Main goal of this series is to be able to detect the following case which apparently is still haunting us. dev_hold_track(dev, tracker_1, GFP_ATOMIC); dev_hold(dev); dev_put(dev); dev_put(dev); // Should complain loudly here. dev_put_track(dev, tracker_1); // instead of here (as before this series) v2: third patch: I replaced the dev_put() in linkwatch_do_dev() with __dev_put().
