Hey.... I may have said this to the list already, but, is it possible to just
make an ioctl() for the block devices that turns off the buffering? Seems a
more elegant solution than having a two device files for every single block
device.

IMHO at least. Probably can't be much worse to implement that the seperate
device file way of doing it.

All this from someone who's never tried acutally writting kernel code himself
of course. :P (learning though....)
