I meant the userspace part is still in development and it largely depends on
how the kernel part plays out. Hence I'm trying to get early feedback here.
The use cases we're aiming at are described in the commit message, is
there anything specific you're looking for in the userspace code? I'm happy
to answer questions you might have.
