I think we've discussed this sometime in the past but what's the
reason for such whitelist consider there's already a get_features()
implemention?
E.g Any reason to block VIRTIO_BLK_F_WRITE_ZEROS or
VIRTIO_F_RING_PACKED?
Thanks
The reason is some feature bits are supported in the device but not
supported by the driver, e.g, for virtio-net, mq & cq implementation
is not ready in the driver.
I understand the case of virtio-net but I wonder why we need this for
block where we don't vq cvq.
Thanks
This is still a subset of the feature bits read from hardware, I leave
it here to code consistently, and indicate what we support clearly.
Are you suggesting remove this feature bits list and just use what we
read from hardware?
Thansk
Yes, please do that.
The whiltelist doesn't help in this case I think.
Thanks
