From 2d746c93b6e55d34a98c8983b30d991707a2059b Mon Sep 17 00:00:00 2001 From: Sowmini Varadhan Date: Thu, 30 Nov 2017 11:11:27 -0800 Subject: [PATCH] rds: tcp: remove redundant function rds_tcp_conn_paths_destroy() A side-effect of Commit c14b0366813a ("rds: tcp: set linger to 1 when unloading a rds-tcp") is that we always send a RST on the tcp connection for rds_conn_destroy(), so rds_tcp_conn_paths_destroy() is not needed any more and is removed in this patch.
