Merge branch 'multipath'

Browse source 
* multipath:
  NFS add callback_ops to nfs4_proc_bind_conn_to_session_callback
  pnfs/NFSv4.1: Add multipath capabilities to pNFS flexfiles servers over NFSv3
  SUNRPC: Allow addition of new transports to a struct rpc_clnt
  NFSv4.1: nfs4_proc_bind_conn_to_session must iterate over all connections
  SUNRPC: Make NFS swap work with multipath
  SUNRPC: Add a helper to apply a function to all the rpc_clnt's transports
  SUNRPC: Allow caller to specify the transport to use
  SUNRPC: Use the multipath iterator to assign a transport to each task
  SUNRPC: Make rpc_clnt store the multipath iterators
  SUNRPC: Add a structure to track multiple transports
  SUNRPC: Make freeing of struct xprt rcu-safe
  SUNRPC: Uninline xprt_get(); It isn't performance critical.
  SUNRPC: Reorder rpc_task to put waitqueue related info in same cachelines
  SUNRPC: Remove unused function rpc_task_reset_client
