Introduce an SPDK vhost FUSE Target to Accelerate File Access in VM...
summary
An SPDK vhost-user-fs target implements virtio-fs over FUSE, backed by blobfs on SPDK and usable with QEMU/Kata and iSCSI/NVMe/NVMe-oF, and demonstrates large throughput — presenters report tens of millions ops/sec in microbenchmarks (they aim for ~2M calls baseline and much higher peaks). The prototype is functional but limited: blobfs supports a narrow file API, lacks xattr and random-write support, struggles with tiny-file workloads and needs more block/commutation maturity.
