Subject: [PATCH 35/51] team: Stop using NLA_PUT*().
Date: Sun, 1 Apr 2012 22:58:25 -0400 [thread overview]
Message-ID: <1333335521-1348-36-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.
