problem with a new block device

Hi everybody !

I'm trying to write a block device driver to emulate harddisk on a
flash memory chip. It's an Intel flash memory on a Teknor motherboard.

We can write on this chip only by 64kB block.
Write acces take long time.
In the life of a chip the number of write acces per block is limited.
(something like one or ten millions acces)

It's why i want to have a full 64kB buffer or a sync before beginning
to write on the chip.

Is it possible to specify to kernel to send only 64kB buffer in
CURRENT->buffer ?

Did anybody have a better idea ?

Thanks a lot

Richard Prescott
