Subject: [PATCH 30/51] crypto: Stop using NLA_PUT*().
Date: Sun, 1 Apr 2012 22:58:20 -0400 [thread overview]
Message-ID: <1333335521-1348-31-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.
Signed-off-by: David S. Miller <davem@davemloft.net>
