Jason Gunthorpe b16de8b9e7 RDMA: Handle the return code from dma_resv_wait_timeout() properly ... ib_umem_dmabuf_map_pages() returns 0 on success and -ERRNO on failure. dma_resv_wait_timeout() uses a different scheme: * Returns -ERESTARTSYS if interrupted, 0 if the wait timed out, or * greater than zero on success. This results in ib_umem_dmabuf_map_pages() being non-functional as a positive return will be understood to be an error by drivers.
