Can you repeat this test, but skip the ext3 snapshot creation part of it
entirely (i.e. create a reiserfs snapshot and an XFS snapshot, without
changing the kernel)?  I'm wondering if XFS is getting an old inode that
ext3 was using, but either ext3 or XFS is not clearing it, so that is why
it is calling into ext3.  Also, are you using ext3 on other filesystems in
this computer?

Cheers, Andreas
