Without a doubt, buffering is useful.  However I question how useful it
is to implement this in individual device drivers instead of once in
mtd_core.c.

Given that you have ignored most of my previous comments, NAK.  I don't
mind merging code that isn't up to our standards yet.  But I have a bad
feeling about a maintainer that does not understand review comments.
Since you had similar problems understanding Andrew, part of the blame
may sit on your side.
