From b30973f877fea1a3fb84e05599890fcc082a88e5 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 6 Dec 2006 20:32:36 -0800 Subject: [PATCH] node-aware skb allocation Node-aware allocation of skbs for the receive path. Details: - __alloc_skb gets a new node argument and cals the node-aware slab functions with it. - netdev_alloc_skb passed the node number it gets from dev_to_node to it, everyone else passes -1 (any node) Signed-off-by: Christoph Hellwig Cc: Christoph Lameter Cc: "David S.
