* [PATCH 25/51] dcbnl: Stop using NLA_PUT*().
From: David S. Miller @ 2012-04-02 2:58 UTC (permalink / raw)
To: netdev; +Cc: David S. Miller

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.

* [PATCH 02/51] wireless: Stop using NLA_PUT*().
From: David S. Miller @ 2012-04-02 2:57 UTC (permalink / raw)
To: netdev; +Cc: David S. Miller
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>
