I wasn't to clear: I will be using 2.4.18. The date in TODO file which
is located in fs/jffs2 directory is 2001/03/01 which seams to be a bit
old. What I would like to now is there a newer (stable) version. (What
to pull out of the CVS - HEAD or some other taged version)

OK I got this, thank you for your help. Just one more thing:

So to mount an empty mtd partition as jffs/jffs2 all I have to do is to
erase it (using erase utilty from mtd)and then just do mount -t jffs2
/dev/mtdblock5 /somedir. Is this correct?
