To be honest, I'd like to see all command processing at user level
(including read/write ... for block devices, it shouldn't be that
inefficient, since you're merely going to say remap an area from one
device to another; as long as no data transformation ever occurs, the
user never touches the data and it all remains in the kernel page
cache).
My ideal for the kernel based infrastructure is a simple tap for
transporting commands addressed to devices upwards (and the responses
downwards). Then everyone can have their own user space processing
implementation that I don't have to care about.
