When a device model's I/O operation fails, we execute the error
action. This lets layers above QEMU implement thin provisioning, or
attempt to correct errors before they reach the guest. But when the
I/O operation fails because its invalid, reporting the error to the
guest is the only sensible action.
This short series does exactly that for virtio-blk. I intend to do
the same for IDE and SCSI.
Markus Armbruster (3):
virtio-blk: Factor common checks out of virtio_blk_handle_read/write()
virtio-blk: Bypass error action and I/O accounting on invalid r/w
virtio-blk: Treat read/write beyond end as invalid
