Hi Josh,

You can't make this change until after patch 3 where you move the reference to virtscsi_handle_event further down.

In other words, if you just apply patch 1 + this patch you will get:

drivers/scsi/virtio_scsi.c:383:13: warning: ‘virtscsi_handle_event’ defined but not used [-Wunused-function]

until you also apply patch 3.  This breaks bisectability.

Please either re-arrange this series so that this is the last patch OR squash patch 2 + 3 together.

If you choose the latter approach and keep this patch then you can also include:
