| Choose Y here to enable Secure RPC using the Kerberos version 5 |
| GSS-API mechanism (RFC 1964). |
| |
| Secure RPC calls with Kerberos require an auxiliary user-space |
| daemon which may be found in the Linux nfs-utils package |
| available from http://linux-nfs.org/. In addition, user-space |
| Kerberos support should be installed. |
| |
| If unsure, say Y. |

| help |
| This option enables a sysctl-based debugging interface |
| that is be used by the 'rpcdebug' utility to turn on or off |
| logging of different aspects of the kernel RPC activity. |
| |
| Disabling this option will make your kernel slightly smaller, |
| but makes troubleshooting NFS issues significantly harder. |

| default n |
| help |
| dprintk() output can be voluminous, which can overwhelm the |
| kernel's logging facility as it must be sent to the console. |
| This option causes dprintk() output to go to the trace buffer |
| instead of the kernel log. |
| |
| This will cause warnings about trace_printk() being used to be |
| logged at boot time, so say N unless you are debugging a problem |
| with sunrpc-based clients or services. |

| help |
| This option allows the NFS client and server to use RDMA |
| transports (InfiniBand, iWARP, or RoCE). |
| |
| To compile this support as a module, choose M. The module |
| will be called rpcrdma.ko. |
| |
| If unsure, or you know there is no RDMA capability on your |
| hardware platform, say N. |
