i.e. basically lazy pinning.
From: mwezdeck
The idea behind the commit:
1. not pin the pages during resource_create ioctl
2. pin the pages on the first use during:
- transfer_*_host ioctl
- map ioctl
3. introduce new ioctl for pinning pages on demand
This change has no impact on user space.

Initial version of shadow virtqueue that actually forward buffers. There

If device supports host notifiers, this makes one jump less (kernel) to
