Careful, careful, careful.
The problem is that pre6 survives quite nicely, but because of the silly typo in __mark_inode_dirty() it won't actually mark inodes dirty. Unless you are actually using the newly integrated raiser-fs, in which case you should be just peachy ;)
Note that the bug is not even noticeable under many loads - especially if you have lots of memory. The inodes just get happily cached for a long time. Which is why I could release a pre6, not even noticing that it's strange and not writing out inode data to the disk.
With a gig of RAM, inodes tend to cache really well.
Now, I'm not saying your filesystem is toast. I'm just saying that if you booted up in pre6, I'd suggest a quick reboot into a better kernel might be a good idea (be a jock, and do a sync and just push the reset button to force a proper fsck when it comes up - just in case).
(And yes, I renamed the pre6's really quickly, so you had to be unlucky to see them.)
