Subject: linux-next: build failure after merge of the final tree (net-next
 tree related)

Hi all,

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

                 from include/linux/icmpv6.h:173,

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:

Subject: [PATCH] net: fix build error in network priority cgroup
 infrastructure

Fixes this error:

                 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

When CONFIG_CGROUPS is not set.
