norm_unmount (*) commit on unmount; the journal is committed
when the file-system is unmounted so that the
next mount does not have to replay the journal
and it becomes very fast;
fast_unmount do not commit on unmount; this option makes
unmount faster, but the next mount slower
because of the need to replay the journal.
bulk_read read more in one go to take advantage of flash
