Subject: [PATCH nf-next] netfilter: nft_lookup: remove superfluous element found check
Date: Tue, 20 Sep 2016 18:22:46 +0200	[thread overview]
Message-ID: <1474388566-12236-1-git-send-email-pablo@netfilter.org> (raw)

We already checked for !found just a bit before:

        if (!found) {
                regs->verdict.code = NFT_BREAK;
                return;
        }

        if (found && set->flags & NFT_SET_MAP)
            ^^^^^

So this redundant check can just go away.
