Date: Wed, 4 Nov 2020 15:11:48 +0100 From: Pablo Neira Ayuso <pablo@...filter.org> To: netfilter-devel@...r.kernel.org Cc: davem@...emloft.net, netdev@...r.kernel.org, kuba@...nel.org Subject: [PATCH net-next 7/8] netfilter: nftables: Add __printf() attribute From: Andrew Lunn <andrew@...n.ch> nft_request_module calls vsnprintf() using parameters passed to it. Make the function with __printf() attribute so the compiler can check the format and arguments.
