From dc3270bc3988e24cdd203d8ebc83cc5e1d7e0385 Mon Sep 17 00:00:00 2001 From: Jeremy Sowden Date: Thu, 3 Oct 2019 20:56:07 +0100 Subject: [PATCH] netfilter: ipset: move ip_set_get_ip_port() to ip_set_bitmap_port.c. ip_set_get_ip_port() is only used in ip_set_bitmap_port.c. Move it there and make it static.
