When the no linger is set, the networking stack sends FIN followed by RST immediately when shutting down the socket. By enabling linger when shutting down we have a proper shutdown sequence on the wire.

I suppose we should introduce a short (how long?) linger pause when shutting down the connection. Thoughs?
Why? I'm not really a TCP expert, but why is this different from say iSCSI or NBD? _______________________________________________ Linux-nvme mailing list Linux-nvme@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-nvme
