The important point being that the kernel is required to stay backwards
compatible with older user utilities--we can't tell people "oh, if
you're upgrading from 2.6.25 to 2.6.26 and you want nfs/rdma to keep
working then you'll also have to upgrade to nfs-utils-1.3.0."

(With maybe some leeway if rdma is still in such an experimental state
that there aren't yet any real users....)
