> > Third, there's no attempt made by mtd to support advanced

I do not expect you, or anybody, to be "impressed" with anything. As I said before, from my
analysis of mtd it will require a great deal of patching to acquire certain functionality. This
will invariably require a large time span, as many people depend on the mtd in it present state.

If your position on the proposed interim solution is definite "no", I'll make an effort to rewrite
the driver in the mtd-friendly way.

This brings me to the first technical question:

mtd_blkdevs breaks the block layer request into separate pages, effectively disabling lower layer
from making decision based on a real data block size, and using dma to any useful extent. What is
the proposed way to deal with this?

(By the way, first question already puts us into a "quirk" area of the statement "smartmedia are
flash chips with quirks". Both memorystick and smartmedia are always operated in tandem with their
controllers, as you could notice.)
