| 26 | Choose Y here to enable Secure RPC using the Kerberos version 5 |
| 27 | GSS-API mechanism (RFC 1964). |
| 28 | |
| 29 | Secure RPC calls with Kerberos require an auxiliary user-space |
| 30 | daemon which may be found in the Linux nfs-utils package |
| 31 | available from http://linux-nfs.org/. In addition, user-space |
| 32 | Kerberos support should be installed. |
| 33 | |
| 34 | If unsure, say Y. |

| 40 | help |
| 41 | This option enables a sysctl-based debugging interface |
| 42 | that is be used by the 'rpcdebug' utility to turn on or off |
| 43 | logging of different aspects of the kernel RPC activity. |
| 44 | |
| 45 | Disabling this option will make your kernel slightly smaller, |
| 46 | but makes troubleshooting NFS issues significantly harder. |

| 54 | help |
| 55 | dprintk() output can be voluminous, which can overwhelm the |
| 56 | kernel's logging facility as it must be sent to the console. |
| 57 | This option causes dprintk() output to go to the trace buffer |
| 58 | instead of the kernel log. |
| 59 | |
| 60 | This will cause warnings about trace_printk() being used to be |
| 61 | logged at boot time, so say N unless you are debugging a problem |
| 62 | with sunrpc-based clients or services. |

| 70 | This option allows the NFS client and server to use RDMA |
| 71 | transports (InfiniBand, iWARP, or RoCE). |
| 72 | |
| 73 | To compile this support as a module, choose M. The module |
| 74 | will be called rpcrdma.ko. |
| 75 | |
| 76 | If unsure, or you know there is no RDMA capability on your |
| 77 | hardware platform, say N. |
