It's there, I put it in yesterday. It's definitely 2.6.34-rc material, I
hope to submit it tonight.

Yeah, it's a bad situation to be in. I changed that BUG_ON() to a
WARN_ON(). I'm not too worried about that part, I'm more worried about
the file system changed. OTOH, they do lack proper flushing now, so it's
likely not a huge risk from that perspective.
