We used in the past the "kABI" notation in the rdma sub system when we 
referred to the ioctl interface that kernel exposes to user space.

See the below [1] from Jason and the below [2] mentioned by Linus as of 
Doug's pull request.

However,
We may better refers to UAPI to make things clearer.

     Merge tag 'for-linus' of 
git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma

     Pull rdma fixes from Doug Ledford:
      "Nothing in this is overly interesting, it's mostly your garden 
variety
       fixes.

       There was some work in this merge cycle around the new ioctl kABI, so
       there are fixes in here related to that (probably with more to come).
