Jeff Layton b4b9d2ccf0 sunrpc: add debugfs file for displaying client rpc_task queue
It's possible to get a dump of the RPC task queue by writing a value to
/proc/sys/sunrpc/rpc_debug. If you write any value to that file, you get
a dump of the RPC client task list into the log buffer. This is a rather
inconvenient interface however, and makes it hard to get immediate info
about the task queue.

Add a new directory hierarchy under debugfs:

    sunrpc/
        rpc_clnt/
            <clientid>/

Within each clientid directory we create a new "tasks" file that will
dump info similar to what shows up in the log buffer, but with a few
small differences -- we avoid printing raw kernel addresses in favor of
symbolic names and the XID is also displayed.

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.

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.

This option allows the NFS client to support an RDMA-enabled

To compile RPC client RDMA transport support as a module,
choose M here: the module will be called xprtrdma.

This option allows the NFS server to support an RDMA-enabled

choose M here: the module will be called svcrdma.
If unsure, say N.
