NFSv4.0: Re-establish the callback channel on NFS4ERR_CB_PATHDOWN
When the NFSv4.0 server tells us that it can no-longer talk to us on the callback channel, we should attempt a new SETCLIENTID in order to re-transmit the callback channel information. Note that as long as we do not change the boot verifier, this is a safe procedure; the server is required to keep our state. Also move the function nfs_handle_cb_pathdown to fs/nfs/nfs4state.c, and change the name in order to mark it as being specific to NFSv4.0. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
