[PATCH v2 00/15] virtio: fix spec compliance issues
Rusty, I have a mind to include this patchset for this merge window.
Any input on this?
This fixes the following virtio spec compliance issues:
1. on restore, drivers use device before setting ACKNOWLEDGE and DRIVER bits
2. on probe, drivers aren't prepared to handle config interrupts
arriving before probe returns
3. on probe, drivers use device before DRIVER_OK it set
Note that 1 is a
