Subject: [PATCH 11/51] nfnetlink_cttimeout: Stop using NLA_PUT*().
Date: Sun,  1 Apr 2012 22:58:01 -0400	[thread overview]
Message-ID: <1333335521-1348-12-git-send-email-davem@davemloft.net> (raw)
In-Reply-To: <1333335521-1348-1-git-send-email-davem@davemloft.net>

From: "David S. Miller" <davem@davemloft.net>

These macros contain a hidden goto, and are thus extremely error
prone and make code hard to audit.
