I think this should be submitted with the user at the same
time. Adding hooks without having a user is not very good.
E.g., you may find out later that this does not help, or
cancel your project, or end up with different call-backs,
etc.

You may keep this patch privately, work on your NAND driver,
and when you have it ready, you submit it with this at the
same time.
