  "message": "sched: Fix detection of empty queues in child qdiscs\n\nSeveral qdiscs check on enqueue whether the packet was enqueued to a class\nwith an empty queue, in which case the class is activated. This is done by\nchecking if the qlen is exactly 1 after enqueue. However, if GSO splitting\nis enabled in the child qdisc, a single packet can result in a qlen longer\nthan 1. This means the activation check fails, leading to a stalled queue.\n\nFix this by checking if the queue is empty *before* enqueue, and running\nthe activation logic if this was the case.\n\nReported-by: Pete Heist \u003cpete@heistp.net\u003e\nSigned-off-by: Toke Høiland-Jørgensen \u003ctoke@redhat.com\u003e\nSigned-off-by: David S.
