From 0a0d93b943a20e4210491911e82c3b4a34391ce4 Mon Sep 17 00:00:00 2001 From: Xin Long Date: Fri, 17 Jul 2020 15:02:30 +0800 Subject: xfrm: interface: use IS_REACHABLE to avoid some compile errors kernel test robot reported some compile errors: ia64-linux-ld: net/xfrm/xfrm_interface.o: in function `xfrmi4_fini': net/xfrm/xfrm_interface.c:900: undefined reference to `xfrm4_tunnel_deregister' ia64-linux-ld: net/xfrm/xfrm_interface.c:901: undefined reference to `xfrm4_tunnel_deregister' ia64-linux-ld: net/xfrm/xfrm_interface.o: in function `xfrmi4_init': net/xfrm/xfrm_interface.c:873: undefined reference to `xfrm4_tunnel_register' ia64-linux-ld: net/xfrm/xfrm_interface.c:876: undefined reference to `xfrm4_tunnel_register' ia64-linux-ld: net/xfrm/xfrm_interface.c:885: undefined reference to `xfrm4_tunnel_deregister' This happened when set CONFIG_XFRM_INTERFACE=y and CONFIG_INET_TUNNEL=m. We don't really want xfrm_interface to depend inet_tunnel completely, but only to disable the tunnel code when inet_tunnel is not seen. So instead of adding "select INET_TUNNEL" for XFRM_INTERFACE, this patch is only to change to IS_REACHABLE to avoid these compile error.
