Introduce an SPDK vhost FUSE Target to Accelerate File Access in...
summary
Implements a userspace SPDK vhost-user-fs target that hooks virtio-fs to SPDK blobfs so QEMU/Kata VMs and containers access host directories via blobfs over NVMe/NVMe-oF/iSCSI. Claims a working prototype with order-of-magnitude throughput gains, reporting up to 2M calls/sec and peaks into tens of millions of IO ops, and shows the data path from fuse requests into SPDK. Notes current limits: limited blobfs API, poor small-file performance, no random-write or xattr support yet.
