Mat Martineau says: ==================== mptcp: Optimize received options handling These patches optimize received MPTCP option handling in terms of both storage and fewer conditionals to evaluate in common cases, and also add a couple of cleanup patches. Patches 1 and 5 do some cleanup in checksum option parsing and clarification of lock handling. Patches 2 and 3 rearrange struct mptcp_options_received to shrink it slightly and consolidate frequently used fields in the same cache line. Patch 4 optimizes incoming MPTCP option parsing to skip many extra comparisons in the common case where only a DSS option is present. ==================== 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.
