4.8-stable review patch. If anyone has any objections, please let me know. ------------------ From: Daniel Wagner <daniel.wagner@xxxxxxxxxxxx> commit 5690a22d8612e1788b48b4ea53c59868589cd2db upstream. 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 <daniel.wagner@xxxxxxxxxxxx> Cc: Anna Schumaker <Anna.Schumaker@xxxxxxxxxx> Cc: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx> Cc: Chuck Lever <chuck.lever@xxxxxxxxxx> Cc: linux-nfs@xxxxxxxxxxxxxxx Cc: netdev@xxxxxxxxxxxxxxx Signed-off-by: Anna Schumaker <Anna.Schumaker@xxxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- 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 -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
