From: Patrick McHardy Date: Tue, 21 Mar 2006 01:12:12 +0000 (-0800) Subject: [NET]: Reduce size of struct sk_buff on 64 bit architectures X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=77d2ca350018c507815f5d38a40ffb597eb9ae25;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git [NET]: Reduce size of struct sk_buff on 64 bit architectures Move skb->nf_mark next to skb->tc_index to remove a 4 byte hole between skb->nfmark and skb->nfct and another one between skb->users and skb->head when CONFIG_NETFILTER, CONFIG_NET_SCHED and CONFIG_NET_CLS_ACT are enabled. For all other combinations the size stays the same. Signed-off-by: Patrick McHardy Signed-off-by: David S.
