From da952315c9c625bd513c6162613fd3fd01d91aae Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 11 Jul 2006 13:50:09 -0700 Subject: [IPCOMP]: Fix truesize after decompression The truesize check has uncovered the fact that we forgot to update truesize after pskb_expand_head. Unfortunately pskb_expand_head can't update it for us because it's used in all sorts of different contexts, some of which would not allow truesize to be updated by itself. So the solution for now is to simply update it in IPComp. This patch also changes skb_put to __skb_put since we've just expanded tailroom by exactly that amount so we know it's there (but gcc does not). Signed-off-by: Herbert Xu Signed-off-by: David S.
