====================
Netfilter fixes for net

The following patchset contains Netfilter fixes for your net tree,
they are:

1) Fix a crash in nf_tables when dictionaries are used from the ruleset,
   due to memory corruption, from Florian Westphal.

2) Fix another crash in nf_queue when used with br_netfilter. Also from
   Florian.

Both fixes are related to new stuff that got in 4.0-rc.
