I'm just a bystander in terms of userspace support, but the current
model always seemed a complete trainwreck to me. Especially as it
implied a public ABI between the core libibvers and the providers, which
caused all kinds of problems. Especially if you userspace guys want
to keep up with the improvements we're doing on the kernel side you
better get up to speed an create a coherent environment :)
