Eric, have you succeeded in reproducing this?

What seems to happen is that while we are in ext3_put_super(), there are still
some inode references held and therefore the inodes (regular files) don't get
deleted and we complain about them in ext3_put_super. The question is who holds
the reference... I did a quick audit of the code and couldn't find iget()
unmatched with iput() or a similar problem.

I guess I can create a debugging patch which might be able to show us who holds
the reference. Will try to code it next week. Mikael, will you be able to run
such debugging patch?
