 (*) == default.
 
-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
+                       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 this option is that corruption of the contents
+                       of a file can go unnoticed.
+chk_data_crc (*)       do not skip checking CRCs on data nodes
+compr=none              override default compressor and set it to "none"
+compr=lzo               override default compressor and set it to "lzo"
