This series implements the following: - Fixes to FMR disconnect recovery - Removal of the insecure ALLPHYSICAL memory registration mode - 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) - 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 is mandated by IT policy. Sagi's proposed fix for mlx4's new FRWR API is included. I'll drop it from my series once the official version of this fix is merged.
