From f9aae95828d3478520f4bd73221bcb450ec1a5c0 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Sat, 2 Dec 2006 22:04:50 -0800 Subject: [NETFILTER]: nf_conntrack: fix helper structure alignment Adding the alignment to the size doesn't make any sense, what it should do is align the size of the conntrack structure to the alignment requirements of the helper structure and return an aligned pointer in nfct_help().
