Question about eliminating virtio-scsi 30s timeout and hot-unplug

Hi Paolo,
I had a question about this patch that eliminates virtio-scsi timeout on
IOs - https://patchwork.kernel.org/patch/9802047/.  How does this work when
we have IOs outstanding to a device that is then hot-unplugged.  I'm under
the impression that those IOs will never get returned with any status
(please correct me if I'm wrong), and we will then end up waiting on them
forever with this patch.

Thanks,
Jason
