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

Hi all,

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

  net/netfilter/ipset/ip_set_hash_gen.h

between commit:

  f66ee0410b1c ("netfilter: ipset: Fix "INFO: rcu detected stall in hash_xxx" reports")

from Linus' tree and commit:

  9fabbf56abfe ("netfilter: Replace zero-length array with flexible-array member")

from the netfilter-next tree.

I fixed it up (see below) 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.

Cheers,
Stephen Rothwell
