Andrii Nakryiko says: ==================== Get rid of two feature detectors: reallocarray and libelf-mmap. Optional feature detections complicate libbpf Makefile and cause more troubles for various applications that want to integrate libbpf as part of their build. Patch #1 replaces all reallocarray() uses into libbpf-internal reallocarray() implementation. Patches #2 and #3 makes sure we won't re-introduce reallocarray() accidentally. Patch #2 also removes last use of libbpf_internal.h header inside bpftool. There is still nlattr.h that's used by both libbpf and bpftool, but that's left for a follow up patch to split. Patch #4 removed libelf-mmap feature detector and all its uses, as it's trivial to handle missing mmap support in libbpf, the way objtool has been doing it for a while. v1->v2 and v2->v3: - rebase to latest bpf-next (Alexei). ==================== 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.
