nftables partially broken after kernel update to 4.16.9

[Bill Sun via arch-general <arch-general@xxxxxxxxxxxxx>]

Hi all,

I just updated one of my computer to 4.16.9. After update, the following
nft commands will not work:
    nft add table ip nat <--- this one works without error
	nft add chain ip nat prerouting { type nat hook prerouting priority 0 \; }
    ^
    This will give me the following error message:
    Could not process rule: Device or resource busy.

However, the default simple firewall still works. I have another
computer that is still on 4.16.8, and the example above works; further,
switching back to a lts kernel (4.14.41) also works.


Any help is appreciated. Thanks.
