If the maintainers merge all the patches I send for the 3.10-rc series, then the 3.10 release should be stable enough to use for testing with data you don't care if you lose. As for the userspace code - that is still just a patchset. I haven't had any feedback from the maintainers about it in the past month, so I've got no idea what they are doing with it. I'll post out a new version in the next couple of days - it's 50-odd patches by now, so it'd be nice to have it in the xfsprogs git tree so people could just pull it and build it for testing purposes by the time that 3.10 releases....
