Martin KaFai Lau says: ==================== This set adds bpf_cubic.c example. It was separated from the earlier BPF STRUCT_OPS series. Some highlights since the last post: 1. It is based on EricD recent fixes to the kernel tcp_cubic. [1] 2. The bpf jiffies reading helper is inlined by the verifier. Different from the earlier version, it only reads jiffies alone and does not do usecs/jiffies conversion. 3. The bpf .kconfig map is used to read CONFIG_HZ. [1]: https://patchwork.ozlabs.org/cover/1215066/ v3: - Remove __weak from CONFIG_HZ in patch 3. (Andrii) v2: - Move inlining to fixup_bpf_calls() in patch 1. (Daniel) - It is inlined for 64 BITS_PER_LONG and jit_requested as the map_gen_lookup(). Other cases could be considered together with map_gen_lookup() if needed. - Use usec resolution in bictcp_update() calculation in patch 3. usecs_to_jiffies() is then removed().

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.
