freebsd stable - Jul 2009 - 7.2-STABLE ZFS: mv: set flags (was: 00000000): Invalid argument

Hi ZFS gurus!

After upgrading my system from 7.2-PRERELEASE to 7.2-STABLE (as
of last week), and accordingly upgrading my Pools from Version
6 to Version 13, I get this error when moving arbitrary files
between different ZFS filesystems.

While this seems not to do much harm (mv returns with 0), it is
annoying. 
Does anybody know an explanation or fix, or is there some work in
progress?

rgds,

.. found my mistake: there are *two* tasks in the upgrade.
Not only zfs pools need upgrade from version 6 to 13 (with
command "zpool"), also the zfs filesystems need upgrade from
version 1 to 3 (with command "zfs"). After doing both, the
message is gone.

I believe this issue was supposed to have been resolved with a path a  
couple weeks ago - (O_EXCL) I had thought it was solved for myself as  
well (except for my vi on 4.8 oddity), but it is not.  :(
