We never had it. Suppose p is allocated in response to an SCSI register
write, and we allocate a scatter-gather list. What do you do if you OOM?
Uh, please do not generalize.
Sorry.
See for instance 29ddf27b72960d6e6b115cd69812c9c57b2a7b13 the incident was
logged and debugged, no OOM, no abort. Not all scenarios admit this, but
claiming that there are none that do is incorrect.
Init is pretty easy to handle. I'm worried about runtime where you
can't report an error to the guest. Real hardware doesn't oom.
