From 0afd4a21ba7d75e93fa79cf05d7a21774e149c0f Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 2 Feb 2009 13:27:44 -0800 Subject: [PATCH] net: Fix userland breakage wrt. linux/if_tunnel.h Reported by Andrew Walrond Changeset c19e654ddbe3831252f61e76a74d661e1a755530 ("gre: Add netlink interface") added an include of linux/ip.h to linux/if_tunnel.h We can't really let that get exposed to userspace because this conflicts with types defined in netinet/ip.h which userland is almost certainly going to have included either explicitly or implicitly. So guard this include with a __KERNEL__ ifdef. Signed-off-by: David S.
