Subject: linux-next: manual merge of the net-next tree with Linus' tree

Hi all,

Today's linux-next merge of the net-next tree got a conflict in:

  include/net/net_namespace.h

between commit:

  2a06b8982f8f ("net: reorder 'struct net' fields to avoid false sharing")

from Linus' tree and commit:

  a30c7b429f2d ("net: introduce per-netns netdevice notifiers")

from the net-next tree.

I fixed it up (see below - but it clearly needs more thought) and can
carry the fix as necessary. This is now fixed as far as linux-next is
concerned, but any non trivial conflicts should be mentioned to your
upstream maintainer when your tree is submitted for merging.  You may
also want to consider cooperating with the maintainer of the conflicting
tree to minimise any particularly complex conflicts.
