From 20af3cfd20145fece208ada7cb10e1fd7f21f128 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Wed, 20 Mar 2013 15:44:27 +1030 Subject: [PATCH] virtio-blk: use virtqueue_add_sgs on req path (This is a respin of Paolo Bonzini's patch, but it calls virtqueue_add_sgs() instead of his multi-part API). This is similar to the previous patch, but a bit more radical because the bio and req paths now share the buffer construction code. Because the req path doesn't use vbr->sg, however, we need to add a couple of arguments to __virtblk_add_req. We also need to teach __virtblk_add_req how to build SCSI command requests.
