From: Anna Schumaker <Anna.Schumaker@xxxxxxxxxx> It's possible for an NFS server to go down but come back up with a different IP address. These patches provide a way for administrators to handle this issue by providing a new IP address for xprt sockets to connect to. This is a first draft of the code, so any thoughts or suggestions would be greatly appreciated!
