From 172a863f2bfbacf4b6bfc06db219b946a058ce1a Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Mon, 15 Oct 2007 01:46:08 -0700 Subject: [PATCH] [NET]: Fix csum_start update in pskb_expand_head I got confused by the dual nature of the off variable in the function pskb_expand_head. The csum_start offset should use nhead instead of off which can change depending on whether we are using offsets or pointers. Signed-off-by: Herbert Xu Signed-off-by: David S.
