But I am wondering why not make it as one subsystem interface, such as nvme ioctl, then the whole implementation can be simplified a lot. It is reasonable because subsystem is exactly the side for consuming/importing the dma-buf.
Yeah that it might be better if it's more nvme specific came to me as well.
The feature is in no way nvme specific. nvme is just the initial underlying driver. It makes total sense to support this for any high performance block device, and to pass it through file systems.
