Martin Lau says: ==================== When a map is storing a kernel's struct, its map_info->btf_vmlinux_value_type_id is set. The first map type supporting it is BPF_MAP_TYPE_STRUCT_OPS. This series adds support to dump this kind of map with BTF. The first two patches are bug fixes which are only applicable to bpf-next. Please see individual patches for details. v3: - Remove unnecessary #include "libbpf_internal.h" from patch 5 v2: - Expose bpf_find_kernel_btf() as a LIBBPF_API in patch 3 (Andrii) - Cache btf_vmlinux in bpftool/map.c (Andrii) ==================== 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.
