Useless debug warning "netlink: 16 bytes leftover after parsing attributes"

Hi,

so lately I am seeing a bunch of these warnings:

netlink: 16 bytes leftover after parsing attributes..

While they give you the process name, they are still useless to track down the message that causes them. I find them even more useless since an updated userspace on an older kernel can trigger the nla_policy warning here. And that updated userspace program is doing nothing wrong by including extra attributes. So what purpose is this warning serving?

Regards
