It needs the XPT_CONG_CTRL flag set on it too--otherwise requests on the NFSv4.1 backchannel are rjected in svc_process_common(): 1191 if (versp->vs_need_cong_ctrl && 1192 !test_bit(XPT_CONG_CTRL, &rqstp->rq_xprt->xpt_flags)) 1193 goto err_bad_vers; Fixes: 5283b03ee5 ("nfs/nfsd/sunrpc: enforce transport...")
