From b529ccf2799c14346d1518e9bdf1f88f03643e99 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 25 Apr 2007 19:08:35 -0700 Subject: [NETLINK]: Introduce nlmsg_hdr() helper For the common "(struct nlmsghdr *)skb->data" sequence, so that we reduce the number of direct accesses to skb->data and for consistency with all the other cast skb member helpers.
