Problems with nftl_format

[Fabrizio Pollastri]

I have a problem with nftl_format. It give the following output to me.

# doc_loadbios /dev/mtd0 grub_firmware (OK: grub prompt appears at next
boot)
# nftl_format /dev/mtd0 81920

My configuration is linux 2.4.3, DOC-2000 16MB @d6000, mtd sanpshot

Most recent snapshots give similar errors. What's wrong?
Thank for any help.

OK, I probably broke it when I changed the structures slightly to make 
sparc64 happy. Can you confirm or deny my suspicion that it broke on the 
17th of March?

Does it start to work again if you recompile nftl_format against the new 
headers?

David,
	I think the problem should be that you have changed the definition
of struct mtd_oob_buf. In older header file you have:

struct mtd_oob_buf {
        loff_t start;
        ssize_t length;  
        unsigned char *ptr;
};

and in newer header file:

struct mtd_oob_buf {
        loff_t start;
        ssize_t length;  
        unsigned char *ptr;
};

But you still use loff_t and ssize_t in mtd_ioctl in mtdchar.c

		ret = (mtd->write_oob)(mtd, buf.start, buf.length, &retlen, 			
databuf);

		if (copy_to_user((void *)arg + sizeof(loff_t), &retlen, 			
sizeof(ssize_t)))
			ret = -EFAULT;

Dose this cause any problem ??
