Well that's rather bad. AFAICT most of the allocations in there are
GFP_KERNEL, so why is this happening?
Because the kernel is producing netlink messages faster than userspace can
consume them, perhaps? If so, the sender needs to block, which means we
need to make reception of these stats a privileged operation?
