.B uid16
Disables 32-bit UIDs and GIDs. This is for interoperability with
older kernels which only store and expect 16-bit values.
.TP
.B journal_data
When the filesystem is mounted with journalling enabled, all data
(not just metadata) is committed into the journal prior to being written
into the main filesystem.
.TP
.B journal_data_ordered
When the filesystem is mounted with journalling enabled, all data is forced
directly out to the main file system prior to its metadata being commutted
to the journal.
.TP
.B journal_data_writeback
When the filesystem is mounted with journalling enabled, data may be
written into the main filesystem after its metadata has been commutted
to the journal. This may increase throughput, however, it may allow old
data to appear in files after a crash and journal recovery.
