help! more message -->jffs2_scan_eraseblock()

["Paul Wong" <paul.wong@digitalview.com>]

Hi!
    i am using a NAND flash to build up the jffs2 file system in Linux
kernel 2.4.17. and get the updated version of the MTD via CVS server. I
followed the NAND doc. and success to control the nand flash component. But,
when using "mount" command to make a device driver. there are more message
to display (like below that). After that, I check the file in jffs2
partition. all files are avaliable in nand flash and good condition.  What
is the meaning about the below message?????

Thank you.

Paul
