Having looked at the set again I already see conflicts in net/core/filter.c
and in linux/bpf.h with things myself and others are working on for net-next.
So I think it makes the most sense to get the whole set via net-next,
since seccomp bits look limited comparing to bpf changes.
Otherwise the merge window will be unpleasant.
