from multiple threads.
That said, probably the most important part is consistency with userptr
in other (non-virtio) drivers, such as Intel and AMD. If they allow
overlapping userptr BOs, then virtio should too; if they do not, then
virtio should also forbid them.

, but thanks for removing the MMU
notifier support. Should the interval tree be added before the feature
is exposed to userspace? That would prevent users who are doing kernel
bisects from temporarily exposing a buggy feature to userspace.

Furthermore, since this is for ROCm and not for graphics, I am less concerned
about supporting systems that require swappable GPU VRAM.
