No, we need to allocate the array larger in that case as want proper

Consider the case of !per_vq_vectors, the size of msix_names is 2, but
snprintf can do out of bound accessing here. (We name the msix shared by
virtqueues with something like "%s-virtqueues" before the patch).
Yes, that's what I meant above - we need to allocate a large array
starting with this patch. I'll fix it up for the next version.

I see.

Thanks
