No fundamental objections.

However, as a followup, netlink_kernel_create() is becomming
function_that_takes_too_many_arguments().

At this point it's better to just pass two arguments, the network
namespace pointer, and a pointer to a "const struct netlink_kern_info"
that holds the rest of the parameters.

Could you make that change too?

Thanks!
