Hello Parav Pandit, The patch fe2caefcdf58: "RDMA/ocrdma: Add driver for Emulex OneConnect IBoE RDMA adapter" from Mar 21, 2012, leads to the following static checker warning:
drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:1426 _ocrdma_modify_qp() warn: bool is not less than zero. drivers/infiniband/hw/ocrdma/ocrdma_verbs.c 1411 int _ocrdma_modify_qp(struct ib_qp *ibqp, struct ib_qp_attr *attr, 1412 int attr_mask) 1413 { 1414 int status = 0; 1415 struct ocrdma_qp *qp; 1416 struct ocrdma_dev *dev; 1417 enum ib_qp_state old_qps; 1418 1419 qp = get_ocrdma_qp(ibqp); 1420 dev = get_ocrdma_dev(ibqp->device); 1421 if (attr_mask & IB_QP_STATE) 1422 status = ocrdma_qp_state_change(qp, attr->qp_state, &old_qps); 1423 /* if new and previous states are same hw doesn't need to 1424 * know about it. 1425 */ 1426 if (status < 0) This check is never true. Based on the comment then the check should be: if (status == 1) return SOMETHING; 1427 return status; 1428 status = ocrdma_mbx_modify_qp(dev, qp, attr, attr_mask); 1429 1430 return status; 1431 } regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
