You're welcome to try our OSD userspace initiator library. It is
v2, but is missing a few bits in r3. It's not a whole file system,
but there are plenty of tests that exercise a broad range of OSD
activity. There's a target there too in case you want to compare
notes. All this is under development.
It uses a linux-specific mechanism to submit the commands to the
in-kernel SCSI midlayer, and from there to your target via iSCSI or
another transport. Large CDBs and bidirectional transfers require
some fairly recent linux kernel features, which are slowly trickling
in to the kernel. You can look at my tree for patches; not all are
needed, and many may have gone upstream already.
