Hi all,

After merging the final tree, today's linux-next build (powerpc allnoconfig)
failed like this:

In file included from include/linux/netdevice.h:53:0,
                 from include/linux/icmpv6.h:173,
                 from include/linux/ipv6.h:220,

                 from include/linux/nfs_fs.h:50,
                 from init/do_mounts.c:20:
include/net/netprio_cgroup.h:23:29: error: field 'css' has incomplete type

And several more similar.

Caused by commit 5bc1421e34ec ("net: add network priority cgroup
infrastructure (v4)").

I have added the following (minimal, but probably not optimal) patch for
today:

From: Stephen Rothwell <redacted>
Date: Wed, 23 Nov 2011 14:49:49 +1100
Subject: [PATCH] net: fix build error in network priority cgroup
 infrastructure

Fixes this error:

In file included from include/linux/netdevice.h:53:0,
                 from include/linux/icmpv6.h:173,
                 from include/linux/ipv6.h:220,
                 from include/net/ipv6.h:16,
                 from include/linux/sunrpc/clnt.h:26,
                 from include/linux/nfs_fs.h:50,
                 from init/do_mounts.c:20:
include/net/netprio_cgroup.h:23:29: error: field 'css' has incomplete type

When CONFIG_CGROUPS is not set.
