Perhaps the above check should stay along with the tx commit code..?

We've already checked that error == 0 here, so this can be simplified.
Hmm.. that said, the original code looks like it commits the transaction
on error != -ENOSPC, which means this slightly changes behavior when
(error && error != -ENOSPC) is true. So perhaps it is the error check
that should be fixed up and not the error2 logic..
