...w and modern pci don't. Given this has been with us for a while I am inlined to look for a global solution rather than tweaking each driver. Given many drivers are supposed to work on legacy too, we know del_vqs includes a reset for many of them. So I think I see a better way to do this: Add virtio_reset_device_and_del_vqs() and convert all drivers to that. When doing this, we also need to/can fix a related problem (and related to the hardening that Jason Wang was looking into): virtio_reset_device is inherently racy: vq interrupts could be in flight when we do reset. We need to prevent handlers from firing in the...
