From 243bb4c6d731f886ac7a99b986e46625f0d5ba07 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Tue, 29 Jan 2013 02:16:18 +0000 Subject: [PATCH] ipv6: Fix inet6_csk_bind_conflict so it builds with user namespaces enabled MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When attempting to build linux-next with user namespaces enabled I ran into this fun build error.

Using kuid_t instead of int to hold the uid fixes this. Cc: Tom Herbert Signed-off-by: "Eric W. Biederman" Signed-off-by: David S.
