Arjun Roy says: ==================== tcp: add CMSG+rx timestamps to rx. zerocopy Provide CMSG and receive timestamp support to TCP receive zerocopy. Patch 1 refactors CMSG pending state for tcp_recvmsg() to avoid the use of magic numbers; patch 2 implements receive timestamp via CMSG support for receive zerocopy, and uses the constants added in patch 1. ==================== Link: https://lore.kernel.org/r/20210121004148.2340206-1-arjunroy.kdev@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.
