I like it, nice work Nicolas.
Applied to net-next.
I did a quick scan and the following jumped out at me as cases we need
to fix up as well:
1) xfrm_user
2) tcp_info
3) taskstats
4) pkt_{cls,sched}
5) openvswitch
etc.
Most of these are statistic cases just like all of the existing ones
we have fixed so far.
