Subject: tcp: do not clear packets_out in tcp_create_openreq_child()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=eb2c80ca87b10814e3067db9c0215701a99dc84f;p=openwrt%2Fstaging%2Fblogic.git

tcp: do not clear packets_out in tcp_create_openreq_child()

New sockets have this field cleared, and tcp_disconnect()
calls tcp_write_queue_purge() which among other things
also clear tp->packets_out

So a listener is guaranteed to have this field cleared.
