IBM's Journaled File System (JFS) for Linux
  
  JFS Homepage:  http://jfs.sourceforge.net/
  
  The following mount options are supported:
  
  iocharset=name	Character set to use for converting from Unicode to
  		ASCII.  The default is to do no conversion.  Use

  		iocharset=utf8 for UTF-8 translations.  This requires

  		CONFIG_NLS_UTF8 to be set in the kernel .config file.
  		iocharset=none specifies the default behavior explicitly.
  
  resize=value	Resize the volume to <value> blocks.  JFS only supports
  		growing a volume, not shrinking it.  This option is only
  		valid during a remount, when the volume is mounted
  		read-write.  The resize keyword with no value will grow
  		the volume to the full size of the partition.
  
  nointegrity	Do not write to the journal.  The primary use of this option
  		is to allow for higher performance when restoring a volume
  		from backup media.  The integrity of the volume is not
  		guaranteed if the system abnormally abends.
  
  integrity	Default.  Commit metadata changes to the journal.  Use this
  		option to remount a volume where the nointegrity option was
  		previously specified in order to restore normal behavior.
  
  errors=continue		Keep going on a filesystem error.
  errors=remount-ro	Default. Remount the filesystem read-only on an error.
  errors=panic		Panic and halt the machine if an error occurs.

  uid=value	Override on-disk uid with specified value
  gid=value	Override on-disk gid with specified value
  umask=value	Override on-disk umask with specified octal value.  For
  		directories, the execute bit will be set if the corresponding
  		read bit is set.
