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.

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.
|
|
|

If unsure, say Y.

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.
