Song Liu says: ==================== s390/bpf: Fix arch_prepare_bpf_trampoline While working on trampoline, I found s390's arch_prepare_bpf_trampoline returns 0 on success, which breaks struct_ops. However, the CI doesn't catch this issue. Turns out test_progs:bpf_tcp_ca doesn't really test members of a struct_ops are actually called via the trampolines. 1/2 fixes arch_prepare_bpf_trampoline for s390. 2/2 adds a check to test_progs:bpf_tcp_ca to verify bpf_cubic_acked() is indeed called by the trampoline. Without 1/2, this check would fail on s390. ==================== Link: https://lore.kernel.org/r/20230919060258.3237176-1-song@kernel.org Signed-off-by: Alexei Starovoitov <ast@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.
