[PATCH v4 04/25] virtio: defer config changed notifications
Defer config changed notifications that arrive during
probe/scan/freeze/restore.
This will allow drivers to set DRIVER_OK earlier, without worrying about
racing with config change interrupts.
This change will also benefit old hypervisors (before 2009)
that send interrupts without checking DRIVER_OK: previously,
the callback could race with driver-specific initialization.
This will also help

[PATCH v2 2/2] rust: virtio: add virtio support
...hen this function is called:
> + extern "C" fn remove_callback(virtio_device: *mut
bindings::virtio_device) {
But I did not find a way to iterate over the the `vqs` member from the
Rust side, i.e.:
```
struct virtio_device {
int index;
bool failed;
bool config_enabled;
bool config_change_pending;
spinlock_t config_lock;
spinlock_t vqs_list_lock; /* Protects VQs list access */
struct device dev;
struct virtio_device_id id;
const struct virtio_config_ops *config;
const struct vringh_config_ops *vringh_config;
struct list_head vqs; <------------------
```
Is there any wrappers o...

[PATCH v4 00/25] virtio: fix spec compliance issues
Changes from v4:
rename virtio_enable_vqs_early() to virtio_device_ready()
Note: Rusty requested we add a BUG_ON in the virtio_ring code.
This can be done by a separate patch on top.
Good for bisectability in case BUG_ON starts triggering :)
Rusty, please review this, and consider for this merge window.
This fixes the following virtio spec compliance issues:
1. on restore, drivers use device
