Subject: netfilter: nftables: Add __printf() attribute
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=35b7ee34abdb722192635528f162ddd8cac25765;p=linux.git

netfilter: nftables: Add __printf() attribute

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.
