Btrfs devel - Jul 2009 - BTRFS warnings on the tons-of-symlinks operations

These warnings occur in the process of creating lots of symlinks before
system hangs (well, this time I was luckier and system didn''t hang..)

I checked: when system hanged, it was always the same offset in the same
function. I failed to get more good traces. I send the best I got.

After lots of attempts I passed the usual hanging step.. With lots of
warnings I already mentioned.
