The res->blob pointer may not be valid (non-NULL) for some blobs where the backing storage is not memfd based. Therefore, we cannot use it to determine if a resource is a blob or not. Instead, we could use res->blob_size to make this determination as it is non-zero for blob resources regardless of where their backing storage is located.
I think this patch is no longer necessary since now you add code to mmap() VFIO storage with "[PATCH v1 7/7] virtio-gpu-udmabuf: Create dmabuf for blobs associated with VFIO devices".
