Sowmini Varadhan says: ==================== RDS: optimized notification for zerocopy completion Resending with acked-by additions: previous attempt does not show up in Patchwork. This time with a new mail Message-Id. RDS applications use predominantly request-response, transacation based IPC, so that ingress and egress traffic are well-balanced, and it is possible/desirable to reduce system-call overhead by piggybacking the notifications for zerocopy completion response with data. Moreover, it has been pointed out that socket functions block if sk_err is non-zero, thus if the RDS code does not plan/need to use sk_error_queue path for completion notification, it is preferable to remove the sk_errror_queue related paths in RDS. Both of these goals are implemented in this series. v2: removed sk_error_queue support v3: incorporated additional code review comments (details in each patch) ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
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.
