From a55d9766cecf2b1b9af4fcf93b2d41b71e599c76 Mon Sep 17 00:00:00 2001 From: "Andrew J. Bennieston" Date: Wed, 4 Jun 2014 10:30:41 +0100 Subject: xen-netback: Move grant_copy_op array back into struct xenvif. This array was allocated separately in commit ac3d5ac2 ("xen-netback: fix guest-receive-side array sizes") due to it being very large, and a struct xenvif is allocated as the netdev_priv part of a struct net_device, i.e. via kmalloc() but falling back to vmalloc() if the initial alloc. fails. In preparation for the multi-queue patches, where this array becomes part of struct xenvif_queue and is always allocated through vzalloc(), move this back into the struct xenvif.
