JFFS2 support LZO/LZMA compression ???

[Clare Huang]

Dear all,

I am a newbie of this community~
According to the http://www.inf.u-szeged.hu/jffs2/compression.php, I know 
BBC could let jffs2 support LZO compression.
But the kernel version I used is 2.6.14.....
How could I patch the kernel or update the mtd driver to support LZO or LZMA 
compression ?

I try to use CVS or git to get the latest mtd driver.....
But I still don't know where to enable the LZO/LZMA support of jffs2 ???

Could anyone help about this ?
or which website I could get more information about this question ?

Thanks and Best Regards,
Clare
