[PATCH v2 3/3] hw/virtio: rename virtio dmabuf API
Posted by Albert Esteve 11 months, 3 weeks ago
Functions in the virtio-dmabuf module
start with 'virtio_*', which is too
generic and may not correctly identify
them as part of the virtio dmabuf API.

Rename all functions to 'virtio_dmabuf_*'
instead to avoid confusion.

I have it fixed in my local branch and passing the tests. I'll wait for
feedback
on the other commits and push a new version after.
