NFS4_OK means that the client acknowledges that it has been given a new limit on the number of recallable objects it can keep. There is no requirement in the text that it should send layoutreturn or that the server should expect that. In any case, there is no reason to make a difference between block, object and file layouts when it comes to CB_RECALL_ANY. The code to handle it should be the same for all. -- Trond Myklebust Linux NFS client maintainer NetApp Trond.Myklebust@xxxxxxxxxx www.netapp.com -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
