AFAICS two issues remain that need to be resolved in the short > term, one way or the other: freeze/restore and full virtqueue. Hi Miklos, We are already handling full virtqueue by waiting a bit and retrying. I think TODO in virtio_fs_enqueue_req() is stale. Caller already handles virtqueue full situation by retrying. Havind said that, this could be improved by using some sort of wait queue or completion privimitve. Thanks Vivek
