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.
