Which version of mkfs.jffs2 could work with kernel-2.4.18+patch-2.4.18-rmk6

[jeffery]

Dear all 
    I’m using the S3c2410x developer board and applied the Kernel-2.4.18
with patch-2.4.18-rmk6 for ARM,
I want to use JFFS2 and used the mkfs.jffs2 that revision is v1.7
    It seems that my mkfs.jffs2’s version is too old so I got many error
message when I mount the mtdblock , the error message is
# mount -t jffs2 /dev/mtdblock1 /mnt
Old JFFS2 bitmask found at 0x00000000
 
You cannot use older JFFS2 filesystems with newer kernels

Further such events for this erase block will not be printed

So Could someone kindly telling me which mkfs.jffs2 version is suitable for
making the jffs2 image ?
