Subject: [PATCH RESEND v4 0/2] virtio-fs: add virtio file system device
Resending now that VIRTIO 1.1 has been published. v4: * Clarify that there are no request ordering guarantees between requests in a single queue [vgoyal] * Add explanation of FUSE session endianness detection [dgilbert] v3: * Remove notifications virtqueue, it's unimplemented and can be added when needed [Miklos] * Add Security Considerations and Live Migration Considerations sections [Michael] v2: * Clean up core virtio file system device spec * Add DAX window These patches add the virtio file system device, which is based on Linux FUSE but includes the DAX window extension. Similar to virtio-scsi, which transports SCSI commands, virtio-fs transports FUSE requests and the protocol documentation is not duplicated here. The DAX window allows file contents to be accessed directly from shared memory. This eliminates copying of data, reduces the number of vmexits, and reduces the guest's memory footprint. It also allows coherent mmap MAP_SHARED semantics between guests on the same host.
