...within virtio.c anyway...
Right, so the double underscores should be ok here, too. (I still do
not like them very much, but that's just my personal taste in this case)

[PATCH RFC v4 00/16] qemu: towards virtio-1 host support
Yet another version of the virtio-1 support patches.
This one has seen some (very) light testing with the virtio-1 guest
support patches currently on vhost-next.
Changes from v3:
- Add support for FEATURES_OK. We refuse to set features after the
driver has set this in the status field, and we allow to fail
setting the status if the features are inconsistent.
- Add missing virtio-1 changes

[PATCH RFC v5 00/19] qemu: towards virtio-1 host support
Another iteration of virtio-1 patches for qemu, as always available on
git://github.com/cohuck/qemu virtio-1
This one seems to work together with the current vhost-next patches
(well, I can ping :)
Changes from v4:
- add helpers for feature bit manipulation and checking
- use 64 bit feature bits instead of 32 bit arrays
- infrastructure to allow devices to offer different sets of feature
bits
