The Btrfs pull request sent in by Chris Mason on Tuesday takes care of a regression in the balance ioctls, an orphan truncate patch to take care of an obscure corruption during xfstests, and problems with sub-volume quotas, plus some other basic Btrfs fixes.
Chris was quick to note though he's still working on a CRC corruption issue and it's a problem that isn't recent. Fortunately, they are at least making progress and are now able to solidly reproduce the problem. "We've been hammering away at a crc corruption as well, which I was really hoping to get into this pull. It isn't nailed down yet, but we were finally able to get a solid way to reproduce. The only good news is it isn't a recent regression."
This latest Linux 3.8 Btrfs pull request can be found on the kernel mailing list.
