RFC5661 doesn't state directly that the client should update the layout stateid if it returns NFS4ERR_NOMATCHING_LAYOUT in response to a recall, however it does state that this error will "cleanly indicate completion" on par with returning the layout. For this reason, we assume that the client should update the layout stateid. The Linux pNFS server definitely does expect this behaviour. However, if the client replies NFS4ERR_DELAY, then it is stating that the recall was not processed, so it would be very wrong to update the layout stateid.
