I feel this race cannot happen anymore. I think the fix for that race was
to introduce the
__LINK_STATE_QDISC_RUNNING bit thus eliminating any races between CPU's. If
CPU has called xmit, the other CPU will enqueue skbs (by holding the
queue_lock) and
exit from qdisc_run since it finds the bit set already.
