David Howells says: ==================== splice, net: Handle MSG_SPLICE_PAGES in AF_KCM Here are patches to make AF_KCM handle the MSG_SPLICE_PAGES internal sendmsg flag. MSG_SPLICE_PAGES is an internal hint that tells the protocol that it should splice the pages supplied if it can. Its sendpage implementation is then turned into a wrapper around that. Does anyone actually use AF_KCM? Upstream it has some issues. It doesn't seem able to handle a "message" longer than 113920 bytes without jamming and doesn't handle the client termination once it is jammed.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
