Merge branch 'filter-next'
Daniel Borkmann says: ==================== BPF updates These were still in my queue. Please see individual patches for details. I have rebased these on top of current net-next with Andrew's gcc union fixup [1] applied to avoid dealing with an unnecessary merge conflict. [1] http://patchwork.ozlabs.org/patch/351577/ ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
