This series implements the following:

- Removal of the insecure ALLPHYSICAL memory registration mode
- Fixes to FMR disconnect recovery
- Significant reductions in per-transport memory consumption
- Support for sec=krb5, sec=krb5i, and sec=krb5p with NFS/RDMA
   (with no performance impact on sec=sys)
- More pre-requisites for device removal support

Kerberos with NFS/RDMA is useful mainly for secure authentication of
each RPC transaction (sec=krb5). The Kerberos integrity and privacy
services are also available, providing feature parity with TCP in
environments where the use of sec=krb5i or sec=krb5p are mandated by
IT policy.
