NFSv4: renewd needs to be able to handle the NFS4ERR_CB_PATH_DOWN error
The NFSv4 spec does not specify that the server must repeat that error, so in order to avoid having the delegations revoked, we should handle it immediately. Also note that NFS4ERR_CB_PATH_DOWN does in fact renew the lease... Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
