[PATCH] [MTD] [UBI] add block device layer on top of UBI

[Nancy]

This patch based on
git://git.infradead.org/users/dedekind/ubifs-v2.6.24.git/  UBI version
  #cd linux-2.6.24/drivers/mtd/ubi
  #path -p1 < ~/ubi_new.diff
  Then copy "ubi_blktrans.h" to linux-2.6.24/include/linux/mtd
  Notice: Please do not select MTD_UBI_GLUEBI

#mkfs.vfat /dev/ubiblock0      works fine, but
#mount -t vfat /dev/ubiblock0 /mnt
mount: mounting /dev/ubiblock0 on /mnt failed: Invalid argument

I grep the whole kernel, can't find where this error come from. I
totally don't know how to debug step by step, I mean follow the mount
application.

Could you please give me a suggestion?  a keyword, a bookname, an
artical link what ever it is.

Many thanks!

Best wishes,
