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.

This commit refactors the existing cgroup program with libbpf bpf loader. The original test_cgrp2_sock2 has keeped the bpf program attached to the cgroup hierarchy even after the exit of user program. To implement the same functionality with libbpf, this commit uses the BPF_LINK_PINNING to pin the link attachment even after it is closed. Since this uses LINK instead of ATTACH, detach of bpf program from cgroup with 'test_cgrp2_sock' is not used anymore. The code to mount the bpf was added to the .sh file in case the bpff was not mounted on /sys/fs/bpf. Additionally, to fix the problem that shell script cannot find the binary object from the current path, relative path './' has been added in front of binary.
