From e3c2ced8d21410e8bc897480081e2ffc516c0f70 Mon Sep 17 00:00:00 2001 From: Julius Volz Date: Fri, 22 Aug 2008 14:06:13 +0200 Subject: IPVS: Rename ip_vs_proto_ah.c to ip_vs_proto_ah_esp.c After integrating ESP into ip_vs_proto_ah, rename it (and the references to it) to ip_vs_proto_ah_esp.c and delete the old ip_vs_proto_esp.c.
