hi  i have a couple questions about the journal in ext3.

1. Will there be performance lose with a smaller journal say 32MB 
instead of 128MB?

2. Is there a way to see free space left in the journal or is it cleared 
at each mount?

3. Is journal_data_ordered atomic like reiser4 where either a 
transaction will happen or it wont happen?
