From 5c34d002dcc7a6dd665a19d098b4f4cd5501ba1a Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Sun, 5 Feb 2017 18:15:18 +0100 Subject: virtio_pci: remove struct virtio_pci_vq_info We don't really need struct virtio_pci_vq_info, as most field in there are redundant: - the vq backpointer is not strictly neede to start with - the entry in the vqs list is not needed - the generic virtqueue already has list, we only need to check if it has a callback to get the same semantics - we can use a simple array to look up the MSI-X vec if needed. - That simple array now also duoble serves to replace the per_vq_vectors flag Signed-off-by: Christoph Hellwig Signed-off-by: Michael S.
