9   This function allows the caller to switch the RPC transport for the
10   rpc_clnt structure 'clnt' to allow it to connect to a mirrored NFS
11   server, for instance.  It assumes that the caller has ensured that
12   there are no active RPC tasks by using some form of locking.

14
15   Returns zero if <span class="quote">&#8220;<span class="quote">clnt</span>&#8221;</span> is now using the new xprt.  Otherwise a
16   negative errno is returned, and <span class="quote">&#8220;<span class="quote">clnt</span>&#8221;</span> continues to use the old
17   xprt.
