Paolo Abeni says: ==================== mptcp: re-enable sndbuf autotune The sendbuffer autotuning was unintentionally disabled as a side effect of the recent workqueue removal refactor. These patches re-enable id, with some extra care: with autotuning enable/large send buffer we need a more accurate packet scheduler to be able to use efficiently the available subflow bandwidth, especially when the subflows have different capacities. The first patch cleans-up subflow socket handling, making the actual re-enable (patch 2) simpler. Patches 3 and 4 improve the packet scheduler, to better cope with non trivial scenarios and large send buffer. Finally patch 5 adds and uses some infrastructure to avoid the workqueue usage for the packet scheduler operations introduced by the previous patches. ==================== Link: https://lore.kernel.org/r/cover.1611153172.git.pabeni@redhat.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.
