Jakub Kicinski says: ==================== net: lockless stop/wake combo macros A lot of drivers follow the same scheme to stop / start queues without introducing locks between xmit and NAPI tx completions. I'm guessing they all copy'n'paste each other's code. The original code dates back all the way to e1000 and Linux 2.6.19. v3: https://lore.kernel.org/all/20230405223134.94665-1-kuba@kernel.org/ v2: https://lore.kernel.org/all/20230401051221.3160913-2-kuba@kernel.org/ v1: https://lore.kernel.org/all/20230322233028.269410-1-kuba@kernel.org/ rfc: https://lore.kernel.org/all/20230311050130.115138-1-kuba@kernel.org/ ==================== Link: https://lore.kernel.org/r/20230407012536.273382-1-kuba@kernel.org 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.
