In that\nwindow the duplicate is stashed into flow->qentry, and then lost when\nsmc_llc_flow_stop() zeros the struct.\n\nCall smc_llc_flow_qentry_del() inside the lock before the memset.\nsmc_llc_flow_qentry_del() already checks flow->qentry before freeing, so the\nnormal case where no entry is pending is a no-op."
