From 7b35eadd7eee2e0b42421ce3efbc30f1c3c745e5 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Fri, 9 Dec 2011 06:21:16 +0000 Subject: [PATCH] inet_diag: Remove indirect sizeof from inet diag handlers 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.
