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
