See my mail about the crash. Agree with your analysis about worker->vtsk
not being set yet. It's a bug from my commit where I should have not set
it so early or I should be checking for
if (dev->worker && worker->vtsk)
instead of
if (dev->worker)
One question about the behavior before my commit though and what we want in
the end going forward. Before that patch we would just drop work if
vhost_work_queue was called before VHOST_SET_OWNER. Was that correct/expected?
The call to vhost_work_queue in vhost_vsock_start was only seeing the
works queued after VHOST_SET_OWNER. Did you want works queued before that?
