Subject: [PATCH 1/13] inet_diag: Remove indirect sizeof from inet diag handlers
Date: Fri, 09 Dec 2011 20:21:16 +0400	[thread overview]
Message-ID: <4EE2357C.2080502@parallels.com> (raw)
In-Reply-To: <4EE23561.5020804@parallels.com>

There's an info_size value stored on inet_diag_handler, but for existing
code this value is effectively constant, so just use sizeof(struct tcp_info)
where required.
