Re: [PATCH/RFC v2] IB: Add SCSI RDMA Protocol (SRP) initiator

[Roland Dreier <rolandd@cisco.com>]

OK, I replaced the function with:

+static int srp_init_qp(struct srp_target_port *target,
+		       struct ib_qp *qp)
+{
+	struct ib_qp_attr *attr;
+	int ret;
+
+	attr = kmalloc(sizeof *attr, GFP_KERNEL);
+	if (!attr)
+		return -ENOMEM;
+
+	ret = ib_find_cached_pkey(target->srp_host->dev,
+				  target->srp_host->port,
+				  be16_to_cpu(target->path.pkey),
+				  &attr->pkey_index);
+	if (ret)
+		goto out;
+
+	attr->qp_state        = IB_QPS_INIT;
+	attr->qp_access_flags = (IB_ACCESS_REMOTE_READ |
+				    IB_ACCESS_REMOTE_WRITE);
+	attr->port_num        = target->srp_host->port;
+
+	ret = ib_modify_qp(qp, attr,
+			   IB_QP_STATE		|
+			   IB_QP_PKEY_INDEX	|
+			   IB_QP_ACCESS_FLAGS	|
+			   IB_QP_PORT);
+
+out:
+	kfree(attr);
+	return ret;
+}
