"Daniel T. says: ==================== Numerous refactoring that rewrites BPF programs written with bpf_load to use the libbpf loader was finally completed, resulting in BPF programs using bpf_load within the kernel being completely no longer present. This patchset refactors remaining bpf programs with libbpf and completely removes bpf_load, an outdated bpf loader that is difficult to keep up with the latest kernel BPF and causes confusion. Changes in v2: - drop 'move tracing helpers to trace_helper' patch - add link pinning to prevent cleaning up on process exit - add static at global variable and remove unused variable - change to destroy link even after link__pin() - fix return error code on exit - merge commit with changing Makefile Changes in v3: - cleanup bpf_link, bpf_object and cgroup fd both on success and error ==================== Signed-off-by: Andrii Nakryiko <andrii@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.
