The following mount options are supported:

iocharset=name	Character set to use for converting from Unicode to
		ASCII.  The default is compiled into the kernel as
		CONFIG_NLS_DEFAULT.  Use iocharset=utf8 for UTF8
		translations.  This requires CONFIG_NLS_UTF8 to be set
		in the kernel .config file.

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.

JFS TODO list:

Plans for our near term development items

   - get access control list functionality operational
   - get extended attributes functionality operational

Longer term work items

   - implement defrag utility, for online defragmenting
   - add quota support
   - add support for block sizes (512,1024,2048)

Please send bugs, comments, cards and letters to linuxjfs@us.ibm.com.
