Alexander Lobakin says: ==================== page_pool: a couple of assorted optimizations That initially was a spin-off of the IAVF PP series[0], but has grown (and shrunk) since then a bunch. In fact, it consists of three semi-independent blocks: * #1-2: Compile-time optimization. Split page_pool.h into 2 headers to not overbloat the consumers not needing complex inline helpers and then stop including it in skbuff.h at all. The first patch is also prereq for the whole series. * #3: Improve cacheline locality for users of the Page Pool frag API. * #4-6: Use direct cache recycling more aggressively, when it is safe obviously. In addition, make sure nobody wants to use Page Pool API with disabled interrupts. Patches #1 and #5 are authored by Yunsheng and Jakub respectively, with small modifications from my side as per ML discussions. For the perf numbers for #3-6, please see individual commit messages. Also available on my GH with many more Page Pool goodies[1].

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.
