What does the block layer need, that it doesn't have now?
Exactly. I'd _love_ for people to really think about this.
In discussion with Jeff, it seems most of what he wants is already
there. He just doesn't know it yet :-)
hehe. Here's a salient point:
native block drivers are typically used in one of two ways: creating a
whole subsystem (ide, scsi), or servicing a single host (dac960).
I am doing the first: creating a whole subsystem. The infrastructure
involved in that, over and above what block already provides, is that
part I dread coding.
If I am to code that, I want to do so ONCE. And that means a
bus-agnostic /dev/{disk,cdrom,tape}. Not /dev/{ad,acd,at,ag}.
