From 50269e19ad990e79eeda101fc6df80cffd5d4831 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Fri, 23 Mar 2012 23:59:33 +0000 Subject: net: add a truesize parameter to skb_add_rx_frag() skb_add_rx_frag() API is misleading. Network skbs built with this helper can use uncharged kernel memory and eventually stress/crash machine in OOM. Add a 'truesize' parameter and then fix drivers in followup patches.
