I would just kill ONFIG_MTD_NAND_VERIFY_WRITE entirely. Some drivers
do not support it and it does not work for sub-pages for long time.
Both UBI and JFFS2 are able to read verify what they wrote already.
There are also MTD tests which do this verification. So I think there
is no reason to keep this in the NAND layer, let alone wasting RAM in
the driver to support this feature.

I am also removing the -stable mailing list - ne need to spam it.
