There is only one waiter for the completion, therefore there is no need to use complete_all(). Let's make that clear by using complete() instead of complete_all(). The usage pattern of the completion is: waiter context waker context frwr_op_unmap_sync() reinit_completion() ib_post_send() wait_for_completion() frwr_wc_localinv_wake() complete() Signed-off-by: Daniel Wagner Cc: Anna Schumaker Cc: Trond Myklebust Cc: Chuck Lever Cc: linux-nfs@vger.kernel.org Cc: netdev@vger.kernel.org Signed-off-by: Anna Schumaker Signed-off-by: Greg Kroah-Hartman --- net/sunrpc/xprtrdma/frwr_ops.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/net/sunrpc/xprtrdma/frwr_ops.c +++ b/net/sunrpc/xprtrdma/frwr_ops.c @@ -329,7 +329,7 @@ frwr_wc_localinv_wake(struct ib_cq *cq, frmr = container_of(cqe, struct rpcrdma_frmr, fr_cqe); if (wc->status != IB_WC_SUCCESS) __frwr_sendcompletion_flush(wc, frmr, "localinv"); - complete_all(&frmr->fr_linv_done); + complete(&frmr->fr_linv_done); } /* Post a REG_MR Work Request to register a memory region Patches currently in stable-queue which might be from daniel.wagner@bmw-carit.de are queue-4.8/xprtrdma-use-complete-instead-complete_all.patch
