commit3a148896b2upstream. Ensure that cv_end is equal to ibdev->num_comp_vectors for the NUMA node with the highest index. This patch improves spreading of RDMA channels over completion vectors and thereby improves performance, especially on systems with only a single NUMA node. This patch drops support for the comp_vector login parameter by ignoring the value of that parameter since I have not found a good way to combine support for that parameter and automatic spreading of RDMA channels over completion vectors.

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.
