The rdma_rw API adjusts max_send_wr upwards during the rdma_create_qp() call. If the ULP actually wants to take advantage of these extra resources, it must increase the size of its send completion queue (created before rdma_create_qp is called) and increase its send queue accounting limit. Use the new rdma_rw_mr_factor API to figure out the correct value to use for the Send Queue and Send Completion Queue depths. And, ensure that the chosen Send Queue depth for a newly created transport does not overrun the QP WR limit of the underlying device. Lastly, there's no longer a need to carry the Send Queue depth in struct svcxprt_rdma, since the value is used only in the svc_rdma_accept() path.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
