From c995ae2259ee36caf48bbfacf40111998dacd4af Mon Sep 17 00:00:00 2001 From: Vijay Subramanian Date: Tue, 3 Sep 2013 12:23:22 -0700 Subject: tcp: Change return value of tcp_rcv_established() tcp_rcv_established() returns only one value namely 0. We change the return value to void (as suggested by David Miller). After commit 0c24604b (tcp: implement RFC 5961 4.2), we no longer send RSTs in response to SYNs. We can remove the check and processing on the return value of tcp_rcv_established(). We also fix jtcp_rcv_established() in tcp_probe.c to match that of tcp_rcv_established().
