hi All my kernel is 2.6.16 after mounting the nand flash with jffs2 partition, the first copy operation for a 15M file(from jffs2 partition to jffs2 partition) take 9 minutes,but the second copy operation takes 1 minutes. the disk usage(df result) is over 85%. I wonder is there any patch ported to such old kernel? Thanks B.R. Jia
