Linux Virtualization - Sep 2019 - [PATCH v2] scsi: virtio_scsi: unplug LUNs when events missed

Matt,
> The event handler calls scsi_scan_host() when events are missed, which
> will hotplug new LUNs.  However, this function won't remove any
> unplugged LUNs.  The result is that hotunplug doesn't work properly
> when the number of unplugged LUNs exceeds the event queue size
> (currently 8).
>
> Scan existing LUNs when events are missed to check if they are still
> present.  If not, remove them.
Applied to 5.4/scsi-queue, thanks!
