From 22609b43b194917dce2188ae9a78bc40a14e67b5 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Fri, 2 Sep 2016 21:00:59 +0200 Subject: [PATCH] netfilter: nft_quota: introduce nft_overquota() This is patch renames the existing function to nft_overquota() and make it return a boolean that tells us if we have exceeded our byte quota. Just a cleanup.
