Christoph,
You're missing the part where actual truncate (reduce i_size)
sets i_size in ocfs2_truncate_file(). So this later code doesn't get
triggered for the truncate case. It exists for the extend case, where
we extend the allocation in multiple clean transactions, then finally
set i_size in a final transaction.
