[JFFS2] Request help on EBS option in Linux-2.6.21.5

[zheng shi]

Hi,

I'm using JFFS2 in linux-2.6.21.5.

When I enabled JFFS2 summary support (EXPERIMENTAL) option, the EBS
mechanism did promote mount time.
But unfortunately files (size>10k) couldn't be written on flash
permanently, i.e., though cp was done, but when remount the file just
copied disappeared.

I have tried -o sync with mount option.

Is there anyone who has encountered the same problem?

BTW, my flash is 2k-page NAND flash.
