Linux kernel source tree
6dd42aa17f
Andrii Nakryiko says: ==================== Based on recent BPF CO-RE, tp_btf, and BPF skeleton changes, re-implement BCC-based runqslower tool as a portable pre-compiled BPF CO-RE-based tool. Make sure it's built as part of selftests to ensure it doesn't bit rot. As part of this patch set, augment `format c` output of `bpftool btf dump` sub-command with applying `preserve_access_index` attribute to all structs and unions. This makes all such structs and unions automatically relocatable under BPF CO-RE, which improves user experience of writing TRACING programs with direct kernel memory read access. Also, further clean up selftest/bpf Makefile output and make it conforming to libbpf and bpftool succinct output format. v1->v2: - build in-tree bpftool for runqslower (Yonghong); - drop `format core` and augment `format c` instead (Alexei); - move runqslower under tools/bpf (Daniel). ==================== 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.
