To compile RPC client RDMA transport support as a module, choose M here: the module will be called xprtrdma. If unsure, say N. config SUNRPC_SWAP bool depends on SUNRPC select NETVM config RPCSEC_GSS_KRB5 tristate "Secure RPC: Kerberos V mechanism" depends on SUNRPC && CRYPTO depends on CRYPTO_MD5 && CRYPTO_DES && CRYPTO_CBC && CRYPTO_CTS depends on CRYPTO_ECB && CRYPTO_HMAC && CRYPTO_SHA1 && CRYPTO_AES depends on CRYPTO_ARC4 default y select SUNRPC_GSS help 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. config SUNRPC_DEBUG bool "RPC: Enable dprintk debugging" depends on SUNRPC && SYSCTL 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. If unsure, say Y.
