[Xen-devel] RE: is a pure usermode backend possible?
I guess it depends on what the specific backend needs to do. I can see that it
makes sense to put a block backend in user space where process scheduling
latency might not be such an issue. Putting a network backend, for instance, in
user space will probably hurt.
