[Qemu-devel] [PATCH V3 0/3] Set correct blk feature for virtio 1.0 |

Hi all:
This series tries to set feature correctly for virtio-blk when virtio
1.0 is supported. Two isssues were addressed according to the spec:
- scsi passthrough was not support in 1.0. This is done through: 1)
let get_features() can fail 2) fail the get_features() when both
scsi and virtio 1.0 is enabled.
- any layout must be set for transitional device. This is done by set
any layout when 1.0 is supported.
Changes from V2:
- Keep scsi=on by default since virtio 1.0 is disabled by default
- Advertise VIRTIO_BLK_F_SCSI unconditionally if virtio 1.0 is
disabled
Changes from V1:
- Split virtio-net changes out of the series
- Enable VIRTIO_BLK_F_SCSI only when scsi is set
- Disable scsi by default and compat it for legacy machine types
- Let get_features() can fail and fail the initialization of
virito-blk when both 1.0 and scsi were supported.
Jason Wang (3):
virtio: get_features() can fail
virtio-blk: fail get_features when both scsi and 1.0 were set
virtio-blk: set VIRTIO_F_ANY_LAYOUT when 1.0 is supported
