 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
+                        media that read faster sequentially
+no_bulk_read (*)        do not bulk-read
+no_chk_data_crc         skip checking of CRCs on data nodes in order to
+                        improve read performance. Use this option only
+                        if the flash media is highly reliable. The effect

+                        of a file can go unnoticed.
