Bi-directional RPC support means code in svcrdma.ko invokes a bit of
code in xprtrdma.ko, and vice versa. To avoid loader/linker loops,
merge the server and client side modules together into a single
module.
When backchannel capabilities are added, the combined module will
register all needed transport capabilities so that Upper Layer
consumers automatically have everything needed to create a
bi-directional transport connection.
Module aliases are added for backwards compatibility with user
space, which still may expect svcrdma.ko or xprtrdma.ko to be
present.
This commit reverts commit 2e8c12e1b7 ("xprtrdma: add separate
Kconfig options for NFSoRDMA client and server support") and
provides a single CONFIG option for enabling the new module.

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 select DEBUG_FS 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.
config SUNRPC_XPRT_RDMA tristate "RPC-over-RDMA transport" depends on SUNRPC && INFINIBAND && INFINIBAND_ADDR_TRANS default SUNRPC && INFINIBAND 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.
