-stable review patch. If anyone has any objections, please let us know. ------------------ From: Bob Breuer In some cases such as: iph->check = 0; iph->check = ip_fast_csum((unsigned char *)iph, iph->ihl); GCC may optimize out the previous store. Observed as a failure of NFS over udp (bad checksums on ip fragments) when compiled with GCC 3.4.2. Signed-off-by: Bob Breuer Signed-off-by: David S.
