  git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git#fuse2

Enable:

CONFIG_FUSE2_FS=y
CONFIG_SAMPLE_FUSE2=y

It's the example loopback filesystem supplied in the git tree above.
I haven't converted libfuse yet to use the new features, so for now
this is the only way to try it.

Usage:

    linux/samples/fuse2/loraw -2 -p -t ~/mnt/fuse/

    options:

     -d: debug
     -s: single threaded
     -b: FUSE_DEV_IOC_CLONE (v1)
     -p: use ioctl for device I/O (v2)
     -m: use "map read" transferring offset into file instead of actual data
     -1: use regular fuse
     -2: use experimental fuse2
     -t: use shared memory instead of threads

I tested with shmfs, and IIRC got about 4-8us latency, depending on
the hardware, type of operation, etc...

Let me know if something's not working properly (this is experimental code).

Thanks,
Miklos
