Daniel Borkmann says: ==================== This series addresses most of the feedback [0] that was to be followed up from the last series, that is, UAPI helper comment improvements and getting rid of the ifindex obj file hacks in the selftest by using a BPF map instead. The __sk_buff data/data_end pointer work, I'm planning to do in a later round as well as the mem*() BPF improvements we have in Cilium for libbpf. Next, the series adds two features, i) a helper called redirect_peer() to improve latency on netns switch, and ii) to allow map in map with dynamic inner array map sizes. Selftests for each are added as well. For details, please check individual patches, thanks!

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.
