Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains three Netfilter fixes for your net tree, they are: * Fix missing generation sequence initialization which results in a splat if lockdep is enabled, it was introduced in the recent works to improve nf_conntrack scalability, from Andrey Vagin. * Don't flush the GRE keymap list in nf_conntrack when the pptp helper is disabled otherwise this crashes due to a double release, from Andrey Vagin. * Fix nf_tables cmp fast in big endian, from Patrick McHardy. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
