Subject: [PATCH 3/9] libxt_quota: require --quota to be specified
Date: Sun, 27 Feb 2011 02:31:13 +0100	[thread overview]
Message-ID: <1298770280-7652-4-git-send-email-jengelh@medozas.de> (raw)
In-Reply-To: <1298770280-7652-1-git-send-email-jengelh@medozas.de>

It is pretty pointless to use -m quota without specifying --quota.
There would be nothing left to count down on.
