Eric Dumazet says: ==================== tcp: add three static keys Recent addition of per TCP socket rx/tx cache brought regressions for some workloads, as reported by Feng Tang. It seems better to make them opt-in, before we adopt better heuristics. The last patch adds high_order_alloc_disable sysctl to ask TCP sendmsg() to exclusively use order-0 allocations, as mm layer has specific optimizations. ==================== Signed-off-by: David S.

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.
