Subject: [PATCH 3/6] netfilter: nfnetlink_acct: report overquota to the right netns
Date: Thu, 18 Aug 2016 19:29:05 +0200 [thread overview]
Message-ID: <1471541348-1538-4-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1471541348-1538-1-git-send-email-pablo@netfilter.org>
From: Liping Zhang <liping.zhang@spreadtrum.com>
We should report the over quota message to the right net namespace
instead of the init netns.
