Chapter 6.3 of spec said
"
Transitional devices MUST offer, and if offered by the device
transitional drivers MUST accept the following:
VIRTIO_F_ANY_LAYOUT (27)
"
So this patch sets VIRTIO_F_ANY_LAYOUT when 1.0 is supported.

Disable scsi passthrough by default since it was incompatible with
virtio 1.0. For legacy machine types, keep this on by default.

If bus_size is less than 0, the command fails.
If buf_size is 0, use DEFAULT_MIRROR_BUF_SIZE.
If buf_size % granularity is not 0, mirror_free_init() will

Currently if qemu is connected to a curl source (eg. web server), and

Implement a real flush instead of faking it. This is especially important
as Qemu assume Write back cashing by default and thus requires a working
cache flush operation for data integrity.

To be safe, when cache=none is used ceph settings should not be able

This is the counterpart for bdrv_open_child(). It decreases the

It is the same as bdrv_open_image(), except that it doesn't only return
success or failure, but the newly created BdrvChild object for the new
child node.
As the BdrvChild object already contains a BlockDriverState pointer (and
this is supposed to become the only pointer so that bdrv_append() and
Block drivers may still want to access their child nodes in their
.bdrv_close handler. If they unref and/or detach a child by themselves,
this should not result in a double free.
There is additional code for backing files, which are just a special
case of child nodes. The same applies for them.

Let the callers of bdrv_open_inherit() call bdrv_attach_child(). It
needs to be called in all cases where bdrv_open_inherit() succeeds (i.e.
returns 0) and a child_role is given.
bdrv_attach_child() is moved upwards to avoid a forward declaration.
